Worcestershire CCC are hopeful of Ben Twohig being fit for the start of the 2020 campaign after suffering an anterior cruciate ligament tear.
The left arm spinner will undergo surgery next week before starting rehab work with the County for the next six to nine months.
He will work with Head Of Science and Sports Medicine Ben Davies and Strengthening and Conditioning Coach Ross Dewar with the aim of being ready to take part in pre-season training for next season if all goes to plan.
Twohig played in seven Specsavers County Championship matches during 2018 in what was a breakthrough season for the 20-year-old.
Worcestershire Head Of Sports Science and Medicine, Ben Davies confirmed: “Ben Twohig had an MRI scan last week which confirmed a diagnosis of an anterior cruciate ligament tear.
“He is due to have surgery on April 16, an arthroscopic procedure, and will then follow rehab for the next six to nine months.
“Ben will undergo the rehab programme with a view to hopefully taking part in pre-season next year for the 2020 season and hitting the ground running.
Worcestershire CEO Matt Rawnsley himself a former left arm spinner with the County, worked with Twohig at various stages of last summer and presented him with his colours on his debut against Surrey at the Kia Oval.
Mr Rawnsley said: “Obviously, for Ben to get this injury is extremely disappointing for him and the club.
“Our medical team is committed to the rehab stage and will endeavour to get him back fit again as soon as possible.”
