Worcestershire CCC Head Coach Kevin Sharp is confident he will have a full Rapids squad to choose from for Vitality Blast finals day on Saturday.
All-rounder Brett D’Oliveira missed the Specsavers County Championship clash with Surrey at Blackfinch New Road with a stiff back.
Key batsman Joe Clarke suffered a similar injury during the game and was unable to field for the last two days of the game.
Overseas player Wayne Parnell split the webbing on his right hand while fielding off his own bowling on the second evening.
Sharp said: “Our physio (Ben Davies) is brilliant. He will get them out there somehow. He is confident.
“He has been working 24 hours a day this week.
“We’ve got a couple of stiff backs to contend with and Wayne split the webbing in his hand.
“But Ben is quite confident Dolly, Clarkey and Wayne will all be out there on Saturday.”
Worcestershire take on Lancashire Lightning in the first semi-final with the winners playing either Sussex Sharks or Somerset in the final.
