The British and Irish Lions face an anxious wait over the fitness of Tomos Williams after the Wales scrum-half limped off in their 54-7 rout of Western Force.

Williams sustained an injury to his left hamstring during the act of scoring the second of his two tries early in the second half at Optus Stadium, ending another impressive performance for the Lions that was propelling him into Test contention.
