British sprinter James Dasaolu's place at next month's World Indoor Championships is in doubt after he suffered an injury scare on Saturday.
Despite winning the 60m event at Sainsbury's Indoor Grand Prix in 6.50 seconds, the 26-year-old clutched his left leg immediately after crossing the finish line.
He later left the track at Birmingham's National Indoor Arena in a wheelchair and with an ice pack on his leg.
Dasaolu told reporters: "My left leg felt tight at about 40-50m. I think it's cramp, but I'll go and see the doctors and see what they say."
The championships get underway in Poland on March 7. The British team is due to be selected on Monday.
