Michigan State is set to hire Colorado‘s Mel Tucker as its next football coach, sources told ESPN.  Tucker, one of several candidates to seemingly turn down Michigan State’s initial overtures, became the focus of the school’s search late Sunday and throughout Monday, sources said. On Saturday, he tweeted that he remained committed to Colorado after speaking with MSU about its coaching vacancy.

A source said Tucker was hesitant to leave Colorado after only one season as the Buffaloes’ coach and attended an event with Colorado donors on Monday in Denver. But Michigan State offered more resources, beyond just annual salary.  An official announcement could come later Wednesday.

The Athletic first reported MSU’s expected hire of Tucker.

The 48-year-old Tucker will replace Mark Dantonio, who announced his retirement last week after 13 seasons at Michigan State. Dantonio, 63, went 114-57 with the Spartans, winning or sharing three Big Ten championships and reaching the College Football Playoff in 2015. He left as Michigan State’s all-time winningest coach but also facing a lawsuit from former recruiting director Curtis Blackwell, who alleges that Dantonio committed multiple NCAA violations.

Tucker, a Cleveland native who played defensive back at Wisconsin, began his coaching career at Michigan State as a graduate assistant for Nick Saban in 1997. He was a defensive coordinator for three NFL teams and served as the Jacksonville Jaguars‘ interim head coach in 2011, going 2-3. Tucker worked alongside Dantonio at Ohio State from 2001 to 2003 and held coordinator jobs at Ohio State and Georgia, before landing his first head-coaching opportunity at Colorado.

Tucker went 5-7 last season with the Buffaloes and last week finalized the nation’s No. 34 recruiting class, according to ESPN
