ANN ARBOR -- Erik Swenson was the longest-tenured commitment in Michigan's 2016 recruiting class.

No longer.

Swenson tweeted Wednesday that he's reopening his commitment due to "unforeseen circumstances."

In a text message to MLive, the four-star offensive tackle said Michigan recently pulled its scholarship offer and canceled his previously scheduled official visit. He said the program did not provide a reason for doing so. He declined to speak further on the matter at this time.

Michigan cannot comment publicly on any unsigned prospects, per NCAA rule.

The 6-foot-7, 285-pound Swenson -- from Downers Grove, Illinois -- committed to Michigan in 2013, when Brady Hoke was the program's head coach.

In an interview with MLive this summer, Swenson explained how it was important to him to stick to his commitment during the program's coaching transition -- because, as he put it, he committed to a school and not necessarily a coach.

"You have to stick with your commitment, you committed to Michigan, you have to honor that," Swenson said in June. "You made a commitment and you have to show you're willing to honor it. There will be ups and downs at any place, and any place you go you'll have to show you can push through them."

Swenson is the second player to decommit from Michigan's class in the past week. Three-star corner Sir Patrick Scott also reopened his recruitment last week.

Michigan now lists a total of 23 public commitments (seven are early enrollees) in its 2016 recruiting class with exactly two weeks to go before signing day.

The number of available scholarships Michigan has to give is currently unclear. The Wolverines finished last season with five free scholarships and saw 13 players graduate without any remaining eligibility. Michigan also lost junior Willie Henry to the NFL draft, and at least three players (Derrick Green, Terry Richardson and Ross Taylor-Douglas) have opted to transfer.
