Two Michigan defensive stars made history over the weekend.

Safety Daxton Hill and defensive lineman Aidan Hutchinson held an autograph at the M Den, a local business in Ann Arbor. The two players are taking advantage of the NCAA’s new policies that allow student-athletes to profit off their name, image and likeness.

The new policies went into effect on July 1. They are the first active Michigan football players to sign autographs. It was also the first time the store offered an autograph signing with current Michigan student-athletes.

Per MLive.com, the two signed autographs for approximately 90 minutes.

The M Den has also partnered with Michigan to sell customized jerseys that feature a players name and number. Previously, jerseys with names on the back could not be sold.

MLive.com also reported that M Den intends to host other signing events featuring current student-athletes in the future.

Across college athletics, this will become more prominent with relaxed NIL rules. Over the weekend, Oklahoma quarterback and Heisman Trophy favorite Spencer Rattler signed autographs at the National Sports Collectors Convention and charged $150 per autograph, per Liz Mullen of Sports Business Journal.
