Middlesex seamer Toby Roland-Jones will miss the rest of the season because of an "ongoing shoulder complaint".
The England right-armer, 32, has not played since September 2019 but had resumed training after a quad strain.
He had injections on Thursday and Middlesex say he will make a full recovery.
Roland-Jones has played 218 times for Middlesex, featuring in four Tests and a one-day international for England in 2017 before suffering back injuries.
In January he signed a new contract with the county until 2022.
