Alex Corbisiero, Jamie Roberts to miss second Test?

British and Irish Lions head coach Warren Gatland has admitted that it is "doubtful" that Alex Corbisiero and Jamie Roberts will be fit to face Australia on Saturday.

Corbisiero suffered a calf injury in the Test win over Australia last weekend, while Roberts was ruled out of the first match with a hamstring problem.

"Alex is struggling a little bit and Jamie is probably in the same boat. Both of them should be fine for the third Test, but at this stage... we have a recovery day tomorrow when everyone's off. Then we'll look at seeing how they are on Thursday morning," Gatland told reporters at a press conference.

"The medics have been doing a fantastic job for us and they might be declared fit, but it's doubtful."

The Lions recorded a 35-0 win over the Melbourne Rebels on Tuesday.
