Warriors fans didn't have to wait for the new "Space Jam" movie to see Klay Thompson return to action ... 'cause after 2 devastating injuries, the NBA superstar is back on the court!!!
Remember, 31-year-old Klay hasn't suited up for the Dubs since tearing his ACL in Game 6 of the 2019 NBA Finals.
Right when he was getting back to 100%, Thompson then tore his Achilles while playing a pickup game in November 2020 ... which kept him from playing in the 2020-21 season.
But Thompson had a breakthrough this week .
