Purdue quarterback Robert Marve has suffered more damage in his troublesome left knee and will miss time, though the full extent of the injury is unknown, Boilermakers head coach Danny Hope said on his radio show Monday night.

Hope said an MRI showed a potential tear in the ACL of Marve's left knee. Marve has had two tears of the same ligament and missed most of the 2010 season because of the injury. The former Miami transfer was granted a sixth year of eligibility before this season.

Hope said the team is optimistic that this tear is not as serious as previous ones and that Marve can return at some point this season.

He started the opener for Purdue in place of the suspended Caleb TerBush, throwing for a career-high 295 yards against Eastern Kentucky. Marve split time with TerBush in Saturday's 20-17 loss at Notre Dame, completing 11 of 18 pass for 119 yards and a touchdown.
