"I would like to express my sincere gratitude ... for all of the love and support shown towards me this past year and a half," Finley said in a Twitter post Thursday. "Being a part of LSU's football team has been a dream come true and is one that I will cherish for the rest of my life.
"Although my time has come to an end as a LSU football player, I wish my former teammates and the coaching staff a successful upcoming season. Change is never easy, but is needed for growth."
Finley told WAFB-TV on Wednesday that he plans on visiting a few other schools before deciding where he'll transfer to.
Brennan opened the 2020 season as LSU's starter and played three games before an abdominal injury sidelined him. Finley then took over, passing for 941 yards with five touchdowns and five interceptions, as LSU went 2-3 during the stretch. Johnson, also a freshman, started LSU's final two games and passed for 674 yards and six touchdowns in wins over Florida and Ole Miss.
The 6-foot-6, 242-pound Finley, a native of Ponchatoula, Louisiana, was a four-star recruit who picked LSU over several other SEC programs.
