Jim Harbaugh appears to be keeping busy during his self-imposed suspension.

The Michigan coach spent Saturday morning working the chains for his 10-year-old son’s football team. Harbaugh’s father, Jack Harbaugh, was also in attendance.

No. 2 Michigan is playing UNLV at home on Saturday in its second of three games without their suspended coach. Harbaugh was suspended by the school for breaking NCAA rules. Special teams coordinator and safeties coach Jay Harbaugh will fill his father’s role in the first half and running back Mike Hart will lead the team in the second half.

The Rebels had four players combine to score five touchdowns in their season-opening, 44-14 victory over Bryant in coach Barry Odom’s debut.
