Kansas senior forward Silvio De Sousa opted out of the 2020-21 college basketball season on Friday to focus on “some personal issues.”De Sousa is best known for his role in a brawl during the closing seconds of a game against Kansas State on Jan. 21. His actions in the melee earned him a 12-game suspension from the Big 12 Conference.”I have a lot of things weighing on my mind and need to address these by taking time for myself and stepping away from basketball,” De Sousa wrote on Twitter. “I do not know what my next plan will be right now, but I will decide that when the time is right.”This was not an easy decision to leave the basketball program, but it’s the best thing for me to do right now.”Kansas coach Bill Self defended his player’s decision.”Today, Silvio informed me he was going to opt out of the 2020-21 season and focus on matters in his personal life,” Self said in a statement. “Knowing Silvio, it was clear he had been distracted and not fully focused during workouts as of late. After he and I sat down and talked about that, it was clear this was the best decision for him, and Kansas basketball, to leave the program. At some point in the future, Silvio will decide what his next steps will be and where that will take him.”Silvio has worked very hard during his time here and we have stood by him throughout, but we fully understand his reasoning to take time away from basketball. We support his decision and wish him nothing but success moving forward.”With about five seconds left in the game on Jan. 21, De Sousa was dribbling to run out the clock when Kansas State’s DaJuan Gordon stole the ball and headed for a layup. De Sousa caught up with him and blocked the shot, sending Gordon to the floor. De Sousa approached Gordon and stared down at him, prompting the fight that brought players from both teams off the bench.
