The England wicketkeeper landed awkwardly going for a catch, and although an x-ray revealed no break, swelling has made his participation in the rest of the Championship match at Edgbaston unlikely.

Director of Cricket Mick Newell said: ?The ankle is quite swollen and it?s unlikely Chris will be able to act as wicketkeeper.

?We?ll have to see how it responds to treatment but at the moment Russell Warren is on standby to take the gloves for Warwickshire?s second innings.

?It doesn?t make much sense to risk Chris on Sunday against Northants in the totesport League either, but we won?t make a definite decision on that until the end of this game.?

Will Smith has been called up from the Second XI to act as 12th man for the rest of the match.
