Fields was the Big 12 Defensive Player of the Year as a freshman in 2012 and "separated" from TCU in July after being accused of assaulting an ex-girlfriend in July.
Fields surrendered to authorities days later after a misdemeanor assault warrant was served.
He only played in three games in 2013 because of suspensions and a foot injury and had 10 sacks and 20.5 tackles for a loss in his two seasons at TCU.
Fields planned to enroll at Stephen F. Austin last year but he was ineligible due to NCAA rules. He ended up at Trinity Valley Community College in Athens, Texas, where he played in 12 games, recording 61 total tackles and 6.5 sacks with two forced fumbles as Trinity Valley went undefeated in 12 games last season.
Fields will sign his letter of intent on Wednesday, with the intention of enrolling in Louisville this summer. He will have two seasons of eligibility remaining.
