Lions boss Warren Gatland concedes that full-back Rob Kearney's hamstring injury is cause for concern.
The 27-year-old was a last minute withdrawal from the Leinster team that beat Ulster in the RaboDirect PRO12 final on May 25 and did not feature for the Lions against the Barbarians on Saturday. The Irishman has also been omitted from the squad that will face the Western Force on Wednesday.
Speaking to the media on Monday, Gatland admitted that their were doubts surrounding Kearney's fitness.
"Rob Kearney's a little bit of a concern for us at the moment. He's got a grade one tear and we will see how he responds. We're potentially prepared that the hamstring injury may not heal as quickly as we might have liked and we will put some other potential plans in place," he said.
"We want to give him a bit of time. We scanned him in Hong Kong and it came back as a grade one tear and the medics have put in a plan for the next week or so. We feel we have cover; we have Leigh Halfpenny and Stuart Hogg while Sean Maitland has played quite a bit at fullback. Potentially if we do get another knock we may have to think about a replacement. There are some markers put in place and if he can hit them then we can potentially bring him back. But it's a little bit concerning at this stage."
Hogg started at full-back against the Barbarians while Halfpenny will wear the number fifteen jersey against the Force.
