Has had a scan on his knee today but says nothing too serious

Yeah, just seen his pic on facebook. As you say, he's says it's not too serious, but he gives no other clue as to whether it will prevent him playing for any length of time. Given that he bothered to have a scan he presumably has some sort of problem. Hopefully he'll be ok.

Maybe that's why he has not been at his best the last few games.

Doesn't worry me particularly, Pittman is a better player, on his day in my opinion. Would make up one decision in Hurst's mind for the play offs. The other being who else to play in midfield, Brown was one of our better players on Saturday, created both goals, but Clay has been more consistent of late. I'd go with Brown because of his terrier like attitude.
