Sam Conners (calf) and Zak Chappell (Achilles) are returning to full fitness while Suranga Lakmal is unavailable for selection after picking up a concussion against Yorkshire
Derbyshire have signed Conor McKerr on loan from Surrey ahead of their County Championship clash with Worcestershire, which begins on June 25.
The club are currently struggling with injuries in their bowling attack, with Sam Conners (calf) and Zak Chappell (Achilles) still returning to full fitness and Suranga Lakmal unavailable for selection after picking up a concussion against Yorkshire at Chesterfield.
McKerr is no stranger to Derbyshire, previously representing the club in 2017, taking 10 wickets in a first-class clash with Northamptonshire, and again in 2021, picking up five wickets in seven T20 Blast outings.

The 25-year-old is yet to represent Surrey in 2023 but did feature twice for Kent in the County Championship in April. He is currently on loan with Nottinghamshire for the remainder of the T20 Blast.
In 21 first-class appearances, McKerr has taken 49 wickets at 32.93.
Derbyshire head coach, Mickey Arthur, said: "A few of our bowlers are carrying minor knocks, but we've been able to move quickly to sign Conor for the game at New Road.
"He's an out-and-out quick bowler and impressed here before, so was a natural fit to slot into the side as we switch to the Championship."
