Sussex have added wicketkeeper-batsman Tim Ambrose to their squad for the crucial Championship match against Warwickshire at Edgbaston starting tomorrow.

Ambrose has scored 154 runs in three appearances in the last ten days after breaking into their Norwich Union League squad.

But with Matt Prior fit again after having five stitches in a cut lip, Ambrose is unlikely to make his Championship debut.

Umer Rashid is back in the squad after recovering from a broken finger but Robin Martin-Jenkins remains a doubt because of the rib muscle injury which has plagued him all season.

The game begins at 10.30 am.

Sussex (from): Montgomerie, Goodwin, Adams, Zuiderent, Yardy, Martin-Jenkins, Prior, Davis, Kirtley, Lewry, Robinson, Ambrose, Rashid.
