No Negri again
Instead, Michael Shank Racing will hold Negri out as he continues to recover from the leg injury suffered in a preseason training accident. Michael Valiante will continue to sub for Negri alongside John Pew.
"We were hoping that everything would be good to go for Detroit, but the doctors think that I should wait a bit longer, so Michael will race with John again this weekend," said Negri. "It really is the hardest thing to do, to be out of the car and not race. But, looking at the long term it is what I have to do so we'll just focus on being at the best I can be when I do get back in the car. We are lucky to have a driver like Michael available like this and hopefully we can have a strong weekend as a team."
Shank's No. 6 Daytona Prototype will once again be driven by Gustavo Yacaman and Antonio Pizzonia, who scored their best finish of fourth in the most recent race at Road Atlanta.
Yacaman has experience at Belle Isle having led 15 laps there last year en route to a win in the Indy Lights race.
"Gustavo and Antonio keep making progress, every race, and hopefully we can help them continue doing that this weekend," team owner Shank said. "Obviously with Gus having won the race here in Lights, he knows his way around pretty well. It was a tough call with Ozz to have him sit out, but doctors' orders are just that so we really appreciate Michael being able to come back and race with us again."
