(Photo: Byron Hetzler, USA TODAY Sports) Now that we know which seven NFL head coaches didn't survive the New Year, the focus has shifted on the potential dozens of candidates who could be in line to replace them. With reports, rumors and additional information coming in rapidly, we'll be keeping track of it all in one place here. Check back regularly for the latest updates of who's on and off the 2013 NFL coaching carousel. GARAFOLO: Andy Reid to interview with Chiefs Arizona Cardinals Replacing: Ken Whisenhunt In the mix: Andy Reid, Ray Horton, Mike McCoy, Lovie Smith The latest: After early reports that the team was close to hiring former Eagles coach Andy Reid, the Arizona Republic now says that it's not quite a done deal. Reid will interview with the team Thursday, a day after meeting with the Kansas City Chiefs. Team president Michael Bidwill also interviewed Cardinals defensive coordinator Ray Horton for the position Tuesday and is scheduled to meet with Broncos offensive coordinator Mike McCoy in Denver this weekend. An NFL Network report listed the Cardinals as one of two teams that former Bears coach Lovie Smith would be most interested in leading. Buffalo Bills In the mix: Ken Whisenhunt, Ray Horton, Hue Jackson, Lovie Smith, Doug Marrone The latest: Bills execs will fly to Arizona this week to interview recently fired Cardinals head coach Whisenhunt as well as his former defensive coodinator Ray Horton for their vacant head coaching job. A source also told USA TODAY Sports that Bengals assistant Hue Jackson will also speak to the Bills next week after his team's wild card game this Saturday against Houston. An NFL Network report listed Buffalo as the other team Smith has the most interest in, while ESPN is saying that Syracuse head coach Doug Marrone will also interview with the Bills. Chicago Bears In the mix: Mike McCoy, Joe DeCamillis, Mike Sullivan, Keith Armstrong, Tom Clements The latest: A variety of reports all indicate that the Bears have focused their initial search on a variety of current NFL assistants. McCoy, Buccaneers offensive coordinator Mike Sullivan and Falcons special teams coordinator Keith Armstrong and Cowboys special teams coordinator Joe DeCamillis will reportedly get interviews. The Chicago Tribune reports that the team would also like to interview Packers offensive coordinator Tom Clements. MIKE DITKA: Firing Lovie Smith was 'stupid' Cleveland Browns In the mix: Chip Kelly, Doug Marrone, Bill O'Brien, Ray Horton The latest: The Browns were one of several teams set to interview Falcons offensive coordinator Dirk Koetter this week until Koetter opted to sign a two-year contract Wednesday to remain in his current job. Patriots offensive coordinator Josh McDaniels also confirmed Monday he'd be staying with New England in that role, leaving the Browns looking at college coaches for the time being. Oregon's Chip Kelly is reportedly the team's top target, according to the Cleveland Plain-Dealer, but he likely won't even address NFL rumors until his team is done with the Fiesta Bowl. Syracuse head coach Doug Marrone will reportedly interview in Cleveland this week while Bill O'Brien remains a potential longshot target. The Browns could also be a third team to interview Cardinals defensive coordinator Ray Horton. Kansas City Chiefs In the mix: Andy Reid, Keith Armstrong The latest: Reid will interview for the Chiefs head coaching job in Kansas City Wednesday while Armstrong will interview with the team at a future time. The Chiefs met with Koetter Tuesday, but his re-signing with the Falcons now takes him out of the running. Philadelphia Eagles In the mix: Chip Kelly, Bill O'Brien, Greg Roman, Bruce Arians, Mike McCoy, Mike Nolan, Keith Armstrong The latest: As USA TODAY Sports' Mike Garafolo noted, "Lurie is saying he's looking for an innovative coach who's ahead of the game and knows where the league is trending." This certainly makes Kelly the team's ideal candidate, with a number of other top coordinators likely in the mix. One of them, Denver's Mike McCoy is reported to be interviewing with the team this weekend. San Diego Chargers In the mix: Bruce Arians The latest: The Indianpolis Colts' offensive coordinator, who led the team during Chuck Pagano's illness this season, is reportedly on the Chargers' short wish list. The team is seeking both a new general manager and coach and may look to hire a general manager who could help with the hiring process first. Arians is unable to interview until next week anyway since his team plays Baltimore in Sunday's AFC Wild Card matchup. PHOTOS: NFL coaching candidates Tags

Kyle Shanahan, Redskins offensive coordinator: The 33-year-old certainly has had a lifetime of experience under his father and will likely get a head coaching opportunity at some point thanks to his work with the young Skins offense.

Joe DeCamillis, Cowboys special teams coach: Even though his unit had several high-profile screwups this season, DeCamillis was courted by the Raiders for their assistant head coaching job last season (the Cowboys denied permission) and might be a darkhorse candidate by some team looking for an unconventional hire.

Andy Reid, former Eagles head coach: Reid has indicated that he’d like to coach in 2013 but it might be better for him to take a year off to recharge after a grueling year on and off the field. San Diego would probably be an ideal landing spot for the Southern California native but the Chargers may not have mutual interest. Robert Deutsch, USA TODAY Sports

Mike McCoy, Broncos offensive coordinator: After adjusting his team’s gameplan to suit Tim Tebow (and win) and then revamping for Peyton Manning, the 40-year-old McCoy is one of the hottest candidates out there. He’s never been a head coach, but Chicago has reportedly already requested an interview and several other teams will likely follow. Byron Hetzler, USA TODAY Sports

Lovie Smith, former Bears coach: Smith is out in Chicago after a 10-6 season and may find an organization happy to pursue someone with his career bonafides. Smith would be a bigger name than any of the Bills’ recent hires and Arizona might kick the tires as well. Andrew Weber, USA TODAY Sports

Doug Marrone, Syracuse head coach: The former Saints offensive coordinator has turned the Orange football program around and is seen as similar to Tampa Bay’s Greg Schiano, who wrapped up his first year in the NFL after bolting Rutgers. With only seven openings, Marrone will have to really wow in interviews to get a job over other potential college guys like Chip Kelly or Nick Saban. Joe Camporeale, USA TODAY Sports

Nick Saban, Alabama head coach: If Saban wins another national title, there’s always a chance that he might decide that he wants another shot at winning a Super Bowl. The former defensive coordinator in Cleveland under Bill Belichick, Saban is likely to at least get a few call from new owner Jimmy Haslam to gauge his interest. Daniel Shirey, USA TODAY Sports

Bill O’Brien, Penn State head coach: O’Brien, the former offensive coordinator in New England, is reportedly high on Cleveland and Philadelphia’s wish lists. Any team who gets him would likely have to pay Penn State a hefty buyout fee to get him out of his contract, which automatically extended to 2020 after the school was hit with NCAA sanctions this summer.

Vic Fangio, 49ers defensive coordinator: Under Fangio’s direction, the 49ers defense has become one of the best in the NFL.

Bob Stoops, Oklahoma head coach: In Norman since 1999, Stoops has no NFL experience and has frequently turned down potential opportunities to make the jump. Only he knows whether his mindset has changed. Stoops did grow up near Cleveland in Youngstown, Ohio, so it would make sense that the Browns might see where his head’s at. Charlie Neibergall, AP
