Thursday's announcement comes a week after news of the suspension first leaked.
This wasn't the first time Winston's off-field actions have made headlines. Here's a timeline of the previous investigations, suspensions and allegations involving his conduct:
Nov. 25, 2012: Winston engages in two BB gun incidents, with one causing $4,200 in damages to a Tallahassee apartment complex.
Dec. 7, 2012: Then-Florida State student Erica Kinsman of Zephyrhills reports being sexually assaulted by a man she later identifies as Winston (then an FSU freshman). Winston maintained that the encounter was consensual. A year later, the State Attorney's Office decided not to charge Winston, citing Kinsman's "problematic" testimony, and a university Title IX hearing found him not responsible of wrongdoing in 2014.
July 2013: A Tallahassee Burger King accuses Winston of stealing soda, but the manager declines to pursue a criminal case against him.
April 30, 2014: Winston is suspended from FSU's baseball team after being cited for shoplifting crab legs from Publix.
Sept. 20, 2014: Winston, a redshirt sophomore, serves a one-game suspension in a prime-time football game against Clemson after making vulgar remarks on campus.
April 16, 2015: Kinsman files a civil suit against Winston from their 2012 encounter. They agree in December 2016 to settle the suit.
March 13, 2016: An Uber driver alleges that Winston groped her in the drive-through of a Mexican restaurant in Scottsdale, Ariz. Winston, coming off his rookie season with the Bucs, denies the allegation, which becomes public through a BuzzFeed report in November 2017. The NFL begins investigating.
Feb. 22, 2017: During a talk to students at St. Petersburg's Melrose Elementary School, Winston says that boys are supposed to be strong but ladies are "supposed to be silent, polite, gentle."
June 28, 2018: The NFL formally announced that it suspended Winston for three games. It concluded that he violated its conduct policy by "touching the (Uber) driver in an inappropriate and sexual manner without her consent."
