Marcel Fassler has been drafted into Corvette Racing’s lineup for this weekend’s Mobil 1 Sportscar Grand Prix at Canadian Tire Motorsport Park due to a hand injury that has ruled out regular driver Tommy Milner from the race.

Milner sustained an injury to his left hand in a crash on the opening lap of Sunday’s Sahlen’s Six Hours of The Glen.

It will mark the first time Milner has missed a race since joining the Pratt & Miller-run squad in 2011.

“My day went from bad to worse Sunday,” Milner said. “Additional tests after my initial exam at Watkins Glen showed an injury to my left hand that will prevent me from competing at Canadian Tire Motorsport Park this weekend.

“On the advice of doctors, there is too much risk for further damage and it would be best to allow time for it to heal.”

A timeline for Milner’s return to the cockpit of the No. 4 Chevrolet Corvette C7.R has not yet been established.

Fassler is the designated endurance driver for the No. 4 car of Milner and Oliver Gavin.

“I’m very sorry for Tommy’s injury,” Fassler said. “I’m sure It is a very difficult and frustrating situation for him, and I hope he is back in the Corvette soon.

“It will be a different experience driving the C7.R around Canadian Tire Motorsport Park than what I am used to at Daytona, Sebring and Le Mans.

“But Corvette Racing is a very close team. We all work well together, so I’m positive the team will do the best job possible helping me get up to speed.”

Team manager Ben Johnson told Sportscar365 on Sunday that the car did not sustain chassis damage in the accident, which came just two weeks after the team’s race-ending crash in the 24 Hours of Le Mans when Fassler was at the wheel that required its spare chassis to be put into use for Watkins Glen.
