Peter O'Mahony an injury doubt for Munster ahead of crunch Champions Cup decider
Peter O'Mahony is Munster’s main injury concern ahead of his side's Champions Cup Pool 4 decider against Castres on Sunday.
The captain limped out of the win over Racing 92 in Paris with an ankle injury last weekend and will sit out today's training session at the University of Limerick.
He is holding out hope of leading his side out at Thomond Park, but is now in a race to be fit for the Pool 4 clash.
"I'm working with the medical staff. I've a couple of things to come through. I'll see how the week goes," he said.
Munster have registered Conor Oliver and Mike Sherry for the Champions Cup and Skerries native Oliver could come into the equation if O'Mahony can't prove his fitness.
Jack O'Donoghue would be the likely replacement in the starting XV, with Oliver coming on to the bench.
"He won't train today," van Graan said of O'Mahony.
"He could possibly play at the weekend. We'll manage him through the week and we'll see in two days' time if he's able to train.
"I'm hopeful he'll be captain on Sunday and lead us out at Thomond Park."
Munster have also welcomed Niall Scannell back to training but he is unlikely to feature this weekend.
He could however come into the equation for Joe Schmidt’s Six Nations squad which is being announced tomorrow.
