Struggling Ant may defy injury to play.
Botha suffered a tweak of his hip flexor muscle in the game against Derbyshire last week.
But the South African is in the squad, along with left-arm, seamer Neil Carter, rested against Derbyshire, as the Bears ponder the balance of a bowling attack which needs to find more bite if it is to force the victory needed to reboot Warwickshire's promotion challenge.
Ashley Giles and skipper Darren Maddy were today leaving a decision late, until they have seen the state of the pitch, before deciding whether to go in with two spinners.
That is the strategy they have favoured most this season but if Botha's hip is troubling him it would be a big gamble to pick him.
The Bears have had enough trouble bowling sides out this season with going a bowler down during games.
Worcestershire's bowling, meanwhile, which has garnered more bonus points than anyone else in Division Two this season, is depleted by injuries.
Simon Jones and Matt Mason are definitely out while Kabir Ali faced a fitness test on his sore back.
ON STANDBY...Ant Botha.
