Stuart Broad will have a scan on his left ankle after he experienced discomfort to an 'ongoing' problem during Nottinghamshire's County Championship match against Worcestershire.
Broad sent down just eight overs in Worcestershire's second innings and spent the final two sessions of the match off the field. He took 2 for 52 off 14 overs in the first innings in what was his first outing since the Test series against Pakistan.
"Stuart's sore ankle has been ongoing and it was stirred up a little bit when he landed in the footholds, so it made sense for him to come off the field when it was too sore for him to bowl," coach Peter Moores told the club website.
"It is manageable, but he has a lot of cricket to play in the rest of the summer. He will have a scan on it this morning.
"It was disappointing for him because he was desperate to get out there and was prowling around the dressing room, but injuries are injuries and you have to take heed of them."
There is still a month until Broad is due to be in England action again when the Test series against India begins on August 1.
His new-ball partner, James Anderson, is currently nursing a shoulder problem which has seen him rested from Lancashire duty in order to be ready to face India over five Tests.
