Gloucester and England centre, Billy Twelvetrees has been called up to the Lions squad as backline cover.
Manu Tuilagi went off injured early in Saturday's game against the Queensland Reds, if his injury specifically is signigicant enough to warrant calling up cover, he could be a major loss to the Lions.
Quoted on the Lions Facebook page, head coach Warren Gatland said:
The nature of a Lions tour means that there will inevitably be knocks which take time to recover from. The whole squad have worked hard but a lot of the backs have doubled up over the last two games, either starting or from the bench. Billy played well in the 1st Test for England and he provides that versatility to cover a variety of positions.
He will meet up with the squad on Friday.
