Worcestershire batsman Jack Haynes is set to be out long-term after suffering a serious ankle injury.
Haynes has had scans on the injury which the club doctor will assess.
“It is a real shame for him, but sadly it is something he is going to have to deal with,” said Worcestershire head coach Alex Gidman.
“It is a serious injury, so it is unlikely Jack will be involved for the foreseeable future. It’s a blow.”
Meanwhile, Pears and England pace bowler Pat Brown will miss the “first few games” of the T20 Blast with a back problem.
