Sam Warburton faces six weeks out of action with “Low-grade medial knee ligament strain” Should be fit for Lions tour if selected
Lions head coach Warren Gatland names his tour party on 19 April, with Warburton tipped to be captain.
“Sam has a low grade strain which will put him out for approximately six weeks,” said Blues coach Danny Wilson.
“It won’t interfere with the Lions.
“If we were fortunate enough to make the second European (Champions Cup qualifying) play-off game, we would envisage him being available for that.
“So he shouldn’t have any problems regarding the Lions.”
