England bowler Graham Onions is a doubt for the first Test against South Africa after picking up a hamstring strain.
Onions, included in England's 13-man squad as an extra pace bowling option, joined his team-mates for warm-ups on Wednesday at the Kia Oval but was not involved in net practice.
He has not yet been ruled out of contention to play, but must be considered a significant doubt for the opener to the three-Test series, which gets under way on Thursday.
The Durham bowler was an outsider to be included as England's third seamer, in any case, with incumbent Tim Bresnan and also Steven Finn likelier choices in most minds.
