Johnson has called a news conference this afternoon to announce a personal injury lawsuit against the university.
It all stems from the September 2009 accident in the weight room, when a bar loaded with 275 pounds fell on Johnson's neck, crushing his larynx.
At the time, it was reported that Johnson was bench-pressing with a spotter when the bar slipped out of his right hand and fell at an angle onto his throat.
Johnson underwent more than seven hours of surgery to repair extensive damage to his neck and larynx.
The running back eventually recovered, but he was out the rest of the season.
The injury didn't prevent him from pursuing work in the pros.
He was picked up by the Tennessee Titans last April as a free agent - a career jump that ended prematurely because of an unrelated ankle injury in the preseason.
