Santa Clara, CA - It appears Jim Harbaugh is ready to return to the college ranks, this time at his alma mater.

Comcast SportsNet Bay Area reports Harbaugh will be introduced as the head football coach at the University of Michigan on Tuesday.

Currently the head coach of the San Francisco 49ers, Harbaugh will guide his team in Sunday's season finale, at home against the playoff-bound Arizona Cardinals.

Reports indicate Harbaugh will accept a six-year, $48 million offer to coach the Wolverines, who fired head coach Brady Hoke after four seasons.

Hoke posted a 31-20 record at Michigan, but never improved on an 11-2 mark and Sugar Bowl title in his first season with the Wolverines.

They went 5-7 overall this season, including 3-5 in the Big Ten, marking the program's first losing season since going 5-7 in 2009 under Rich Rodriguez.

The 51-year-old Harbaugh has led the 49ers to a 43-19-1 mark over his four seasons. That includes a Super Bowl loss to the Baltimore Ravens following the 2012 season. The 49ers also made the NFC Championship Game in the 2011 and 2013 seasons, losing to the New York Giants and Seattle Seahawks, respectively.

This season, though, the 49ers are 7-8, and have already been eliminated from postseason contention.

Harbaugh, who has one year left on his contract with the 49ers, coached at Stanford for four seasons (2007-10) and at San Diego for three (2004-06). He led the Cardinal to an Orange Bowl win over Virginia Tech in his final season at Stanford before leaving to coach the 49ers.

Harbaugh played 177 games as a quarterback in the NFL, beginning his 15-year career with the Chicago Bears and also spending time with the Colts, Ravens, Chargers and Panthers. Before that, he was a standout QB at Michigan under legendary coach Bo Schembechler. He played for the Wolverines from 1983-86.

Harbaugh is the son of longtime college coach Jack Harbaugh and the brother of Ravens head coach John Harbaugh.
