And that could spell disaster for Michigan football as it tries to keep the Lausanne standout running back for its 2019 class.
Gray, a four-star prospect, will take an unofficial visit to Tennessee on Saturday to attend the Volunteers' game with Missouri. It will be his third trip to see the Vols this season, according to 247Sports. Gray took an official trip on Sept. 22 when the Vols played Florida and an unofficial on Oct. 20 when the Vols hosted Alabama.
Gray had originally planned on visiting Michigan on Saturday. However, Gray told the USA Today Network - Tennessee that his commitment to Michigan is wavering.
