Lions 2013: Sam Warburton to have knee injury assessed
British and Irish Lions captain Sam Warburton is a doubt for Saturday's tour opener against the Barbarians.
Assistant coach Rob Howley said the Wales flanker picked up a knock on his knee and will continue to be assessed after missing Wednesday's training.
Prop Gethin Jenkins has already been ruled out of the opening warm-up match in Hong Kong with a calf injury.
The Barbarians announced their line-up on Wednesday, with Italy number eight Sergio Parisse named captain.
The invitational team also features ex-All Blacks Joe Rokocoko and Nick Evans, France scrum-half Dimitri Yachvili and Springboks hooker Schalk Brits.
The Barbarians game is the first of six warm-up matches before the first Test against Australia in Brisbane on 22 June.
The Barbarians were beaten 40-12 by England on Sunday, although only four players from that side remain.
