Gervin spent the last four seasons with the Spartans, playing in 23 games with nine starts. He finished his career with 44 tackles, four passes defended and one touchdown on a fumble recovery.
The 5-foot-11, 190-pound Gervin started two games earlier in this season for the unbeaten Spartans, but was replaced in the lineup after a tough afternoon against Miami in the middle of September. Gervin announced his decision to leave Michigan State on Sept. 26 after appearing only on special teams in a win over Nebraska.
Wisconsin is familiar with Gervin, having offered him a scholarship when he was in high school at Cass Technical in Detroit. Gervin will be allowed to play starting next fall and he’s got two years of eligibility left.
