Tomas O’Leary became the first injury worry for British & Irish Lions coach Ian McGeechan as he was carried off on a stretcher at Musgrave Park on Friday night.
Munster’s Magners League game against the Scarlets was only seven minutes old when the Irish scrum-half was injured in open play.
With his hands holding his head, the medics treated his left leg as he was carried from the field.
Minutes earlier it hade been the 25-year-old’s astute pass that had led to Ian Dowling’s first try as Munster maintained their push for the Magners League title.
O’Leary was one of three scrum-halves named by McGeechan in his 37-man squad on Tuesday afternoon.
Should he be ruled out of the tour, then Scotland skipper Mike Blair or compatriot Chris Cusiter, Wales’ 2005 Lions Test No9 Dwayne Peel, England’s Danny Care and even O’Leary’s Munster team-mate Peter Stringer could come into the reckoning to join Harry Ellis and Mike Phillips in South Africa.
