I know what you mean - but, when was the last time that MB played?  Without checking, it was probably a month ago.  Also, he was coming back from injury then.  I'm worried that he could be a bit rusty as he hasn't had any significant game time this season.

Actually, as I was typing, I looked it up:
01/09   Sale Sharks
29/09   Gloucester Rugby
06/10   Saracens
13/10   Agen
TOTAL 320 minutes
I'm not 100% sure this is correct though - as I though he went off with an injured wrist in one of the games.
