Munster star Conor Murray will have his fingers crossed for good news when he meets knee specialist Ray Moran at the Sports Surgery Clinic in Santry, Dublin for the results of the scan on his right knee.
The scrum-half was forced from the field in the first half of Munster's 21-18 victory over the Ospreys at Thomond Park on Saturday with injury to the medial ligament in his right knee.
While Munster will be anxious to have his services for their Pro12 final against Glasgow on Saturday, Head Coach Anthony Foley was quick to point out the fine form of his understudy Duncan Williams.
Speaking this afternoon in Limerick, Munster head coach Anthony Foley said: "Conor got a scan yesterday so we're waiting. He's going to see Ray and from there we'll get an assessment and a judgement on the damage done and whether he's available to train on Thursday or not.
"If he is, he is. If he isn't, Duncan Williams (who replaced him last Saturday) will step up and Cathal Sheridan will come into the squad as well.
"Duncan has played a hell of a lot of rugby for us this year and he's played really well. He's grown into the side and people have grown around him as well in understanding his way of playing. It suits a lot of people."
He added: "Look, it's over time as you see the injury, you slow it down, you look at it again and again. You kind of go, 'there could be a bit of damage there'. It's not often you see a player walk off the pitch like that early in a semi-final and they get back the following week
"You hope that you get some good news, but if not we're used to having to make changes. We're used to having to use our squad and in fairness they haven't let anyone down this year."
Simon Zebo was also forced from the action on Saturday after a heavy fall left him with a black eye and concerns over possible concussion but his recovery appears to be coming along well.
“He was active today, no symptoms, so hopefully tomorrow he ups the activity level and then on Thursday trains with us,” said Foley of Zebo, who has enough time to fully complete the protocols before the Glasgow game.
Foley said that there are a number of tired bodies in the squad after a long season. Some players did not take part in training today with the management team taking a sensible approach regarding player workload in preparing for Saturday's PRO12 decider.
Regarding skipper O'Mahony's hip flexor issue, he said: "Peter is looking fine, but we need to see what he looks like after today's session. We're minding him at the moment and we'll see where he is on Thursday."
