The Suns guard tore the ACL in his left knee and could miss the entire season, the team announced on Tuesday afternoon. The injury was sustained last week when Knight was playing in Southern Florida, according to the team release.
He will undergo surgery, and an official timetable for his return will be determined at a later date, the team said.
Knight, who has three years and almost $44 million remaining on his contract, averaged 11.0 points and 2.4 assists per game last season.
The year prior, he registered 19.6 points, 5.1 assists and 3.9 rebounds per contest. It looked like there was a path for Knight to bounce back this season, but the injury derailed any chances to do that. Other than that, the Suns haven't gotten much attention over the past few seasons since they've failed at winning basketball games and basically have underachieved.
