He seems almost to have made the grade but not quite:

No sign that another county has picked him up yet, which is a shame.

Actually surprised this has only just been announced, he had dropped out of the second team in the latter stages of last season, and played some games for SACA, which would not have happened if Warwickshire were going to invest in him with a new contract.

Dismissed for 24 playing for SACA at Derbyshire today.

Mo Johal, I Mohammed and Waqas Khan are also in the SACA side.
