Paceman Chris Russell has been added to the Worcestershire squad for tomorrow's crucial Royal London Cup clash with Gloucestershire at New Road.
Russell was the county's leading wicket-taker in the NatWest T20 Blast with 16 victims in eight appearances.
He is in contention to start his first One-Day Cup clash of the campaign after recovering from a recent side strain.
Director Of Cricket Steve Rhodes has named a 13 strong squad – the 11 in action in the abandoned match with Hampshire at the Ageas Bowl last night plus Russell and Tom Fell.
Worcestershire are currently lying in fifth position in the table with two matches to play – against Gloucestershire and Thursday's meeting with Leicestershire at Grace Road.
The top four go through to the quarter-finals with the leading two in each group having home advantage in the last eight.
Rhodes has to decide who will open in place of Richard Oliver who has been left out of the One-Day Cup squad for the second successive match.
He admits everyone is coming to terms with playing 50 over cricket this season after it has replaced the 40 over game.
Rhodes said: "It is different to 40 over cricket without a doubt with the new rules and all of us are coming to terms with playing this format, Daryl Mitchell as captain as well.
"There is a lot of learning curve there for him as a captain.
"It is quite tough cricket and is completely different to the 40 over game and the international rules of the two new balls and the four men outside the circle.
"If you get guys in, that last 10 overs is an absolute nightmare. "
