It's down to the wire now for the five contenders who have been shortlisted for the ultimate individual accolade in northern hemisphere rugby, ERC European Player of the Year 2013.
But the 36-year-old suffered a recurrence of the injury whilst training this week and will have to wait to see the full extent of the damage.
"Martyn has had a recurrence of the injury, which is very disappointing," said Blues coach Justin Burnell.
"He's been set back for another period.
"He had a knock on his arm during a very physical session which was required for the squad.
"So he's gone back now to have more X-rays.
"We could be without him for a fair while. He's gutted. I felt very sorry for him because we had included him in the squad for this weekend.
"With that and having had this fresh knock, I can understand his total frustration and disappointment. I really feel for him because he's been very supportive of the players, management and coaching staff while he has been out.
"He's been outstanding for us actually."
