Michigan welcomed in a potential huge addition to its offensive aresenal this week in the form of ex-USC running back Ty Isaac.

Scout.com's Sam Webb first reported that Isaac, and his parents, made their way to Ann Arbor to take in a visit with Brady Hoke and the Wolverines on Tuesday. Webb later reported that Isaac's one-day visit turned into an overnight trip, with him staying in town through at least Wednesday morning.

The former USC back and five-star recruit received his release from the Trojans last month so that he could transfer closer to his native Shorewood, Ill. as his mother works through complications from a recent surgical procedure.

Isaac is seeking a hardship waiver from the NCAA to play immediately. In order for that waiver to be granted, under current rule, Isaac would have to transfer to a school within 100 miles of his home in Shorewood.
