Australia's Remy Gardner has apologised for his role in an opening-lap crash in Moto2™ at the Czech Republic Grand Prix.
Gardner, Joan Mir and Bo Bendsneyder were involved in the incident, which retired all three riders.
Despite making up several places after starting from 19th on the grid, Gardner was left empty-handed at Brno.
"After qualifying I knew I needed a good start," said Gardner.
"I got off the line well and made up a few places on the opening couple of corners.
"When I got to Turn 5 Mir slowed mid-corner, I sat the bike up to try to miss him but I had nowhere to go and we went down.
"It's an unlucky way to end the weekend on the first lap but I just have to look ahead to the next one.
"I'm sorry to Joan and to Bo, who was also caught up in the incident, but as I say I wasn't trying to make a pass or do anything stupid early on.
"It's just really unlucky."
Moto2™ moves straight to the Red Bull Ring this weekend for Austrian Grand Prix.
