McGrath injury worry for Lions

Leinster prop Jack McGrath became the latest Lions concern for Warren Gatland after going off ten minutes into the PRO12 semi-final.

McGrath may undergo an x-ray on his right arm to assess the extent of his injury. Mako Vunipola and Joe Marler are the other loosehead props in Gatland's squad.

"Jack got a whack on his arm so we’ll see how he is. He may need to get an x-ray but again, we’ll see how he settles down," Leinster boss Leo Cullen told

“It’s very early to say. He has an ice pack on his arm. He just lost a bit of power there so we’ll see how he is.”

Leinster's other Lions prop, Tadgh Furlong, left the field with cramp and Cullen added that he did believe there would be any reason to worry.

Sean O'Brien, originally named on the bench for Friday's game, was withdrawn as a precaution before kick-off on Friday.

“He trained earlier in the week and reported on Wednesday, but we thought it might turn around on Thursday,” said Cullen. “He was down here for the team run [on Thursday], still felt a little bit tight so we made the call to pull him from the game.

“It doesn’t seem too bad but we didn’t take any risks with him, just with his soft tissue injury history.”
