Isaac (knee) was diagnosed with a torn left ACL after undergoing an MRI following Sunday's 132-116 win over the Kings, Adrian Wojnarowski of ESPN reports.
Playing in his second game in seven months after previously suffering a severe sprain of the same knee, Isaac will now miss the remainder of the 2019-20 season as a result of the devastating setback. While the NBA has yet to unveil its schedule for the 2020-21 season, his rehab will more than likely keep him out for the bulk of the upcoming campaign, as well. Prior to the initial injury, Isaac had emerged as one of the most improved players in the league, particularly on the defensive end. He'll wrap up his third season in the NBA with averages of 2.3 blocks and 1.6 steals in 28.8 minutes per game.
