Young Jamaican sprinters Oblique Seville and Ackeem Blake as well as American 400m hurdles star Dalilah Muhammad have been forced to withdraw from the Racers Grand Prix.
The meet, which has been designated a World Athletics Continental Silver event, makes its highly-anticipated return on Saturday at the National Stadium, with a host of local and international stars set to compete.

Sprinting superstar Shericka Jackson, hurdling standout Hansle Parchment, long jump star Tajay Gayle, sprint hurdler Megan Tapper and triple jumper Shanieka Ricketts will carry the Jamaican flag at the meet.
The Racers Grand Prix gets going at 6:00pm.
