Gophers football defensive graduate assistant Clint Cosgrove, 26, was booked on impaired driving charges on Friday morning. Cosgrove faces third-degree DWI charges after failing to comply with South Lake Minnetonka police attempts to issue a chemical test. Cosgrove was released after spending more than four hours at Hennepin County jail. He is scheduled to appear in court Dec. 15. Cosgrove works with the Gophers defensive backs under Ronnie Lee, co-defensive coordinator and defensive backs coach. CosgroveâÄôs official duties with the team include breaking down film and preparing the defense for upcoming games. University of Minnesota graduate assistants like Cosgrove are typically enrolled in a graduate program at the University, though it could not be confirmed whether or not Cosgrove is currently enrolled. This year, Cosgrove, son of Gophers Co-Defensive Coordinator Kevin Cosgrove, entered his third season with the Gophers football program. CosgroveâÄôs arrest is another black eye for the GophersâÄô football program, which has had its share of off-field woes this season. In the early morning hours on Sept. 27, Gophers sophomore linebacker Gary Tinsley fled the scene of a Dinkytown fight and was later caught by University police and cited for underage drinking and fleeing from police. On Nov. 3, Gophers defensive back Michael Carter was arrested and charged with underage drinking and obstructing the legal process. Carter allegedly attempted to pick a fight outside of a Dinkytown eatery. Neither Tinsley nor Carter has been suspended. A spokesman for the University Athletics Department declined to comment on CosgroveâÄôs incident due to its personal nature and said there would be no official statement. -Briana Bierschbach contributed to this report.
