WILLIAMS INJURY MARS BIG WIN FOR THE LIONS

THE British and Irish Lions claimed their first victory on Australian soil by overwhelming Western Force 54-7, but a possible injury crisis is brewing at scrum-half after Tomos Williams was forced off.

Williams was among the Lions' star performers at Optus Stadium but his match was over when he injured his left hamstring during the act of finishing his second try in the 47th minute.

The Wales half-back limped from the pitch to leave the Lions sweating on his fitness given Jamison Gibson-Park has yet to play on tour because of a glute problem, potentially leaving Alex Mitchell as the only available option in the position.

Gibson-Park is expected to make his comeback against the Reds in Brisbane on Wednesday but with Williams struggling and Alex Mitchell facing the prospect of playing in a third consecutive game, head coach Andy Farrell may be forced to call up a reinforcement.

"Tomos has come off holding his hamstring. There was plenty of cramp last week, let's hope it is one of those," Farrell said.

"Jamison is fit and ready to go and has been training fully for the best part of a week so we're happy with that but we will only know in the morning.

"You have to let these things settle down and see what the outcome is and give it a little bit of space.

"Tomos was playing well and I'm sure there is a bit of concern there, but you can only deal with the here and now so fingers crossed."
