The Warriors scrum-half was unable to take part in the Scotland squad training session at Murrayfield today due to the knock he picked up against Sale Sharks last week.
Despite having no chance of qualification for the knockout stages, Graeme and his team-mates are desperate to atone for their embarrassing 45-3 flop at Heywood Road.
He told the Evening Times: "We played badly again. The pattern of our recent games continued; we didn't take our chances, we made silly mistakes and we paid the consequences. Sale are third in the Zurich Premiership and are a very good team. When we missed a tackle they scored a try.
"Whenever we gave them opportunities they took them and we got what we deserved. Having said all that, I don't think they were 40 points better than us. We have got to be positive going in to our final game against Llanelli this week. We only have personal pride at stake.
"But that was all Sale had to play for last week and they were certainly motivated - there is no reason at all why we can't beat Llanelli. We are at home and that is a huge advantage for us. We can give the Glasgow fans something to cheer about."
