The news was first reported by WTKA and GoBlueWolverine.com and confirmed by a member of the school’s athletic department.
Miller would have been a fifth-year senior.
"Jack has decided to forego his final year of eligibility to focus on studies and pursue business opportunities," according to Michigan associate athletic director Dave Ablauf. In his three seasons, Miller made 16 starts, including all 12 games last season.
Miller anchored a line that gave up only 26 sacks and running attack that averaged 4.6 yards per carry. Miller said in Twitter post that the decision not to return to the team was “difficult” but that he had accomplished all of his goals.
“I will graduate with a free education from the best public university in the world and have played a lot of football at the highest possible level. It is time to start the next chapter of my life," Miller said. "I'm am eternally grateful for the opportunity Michigan has given me. Thank you to everyone who has made this dream come true."
