Golden State Warriors shooting guard Klay Thompson has undergone successful surgery on his right Achilles, per Adrian Wojnarowski of ESPN.

Thompson tore his Achilles while playing in a pick-up game in Los Angeles. He will miss the entire 2020-21 season for the Warriors, who acquired small forward Kelly Oubre Jr. from the Oklahoma City Thunder after the injury news broke.

The entire NBA world was devastated to see Klay Thompson get hurt, especially since he sat out the 2019-20 season rehabbing his left ACL tear. It's impossible to understand what the Warriors star is going through emotionally and mentally, as he's now set to miss 164 games in a row.

The Warriors, who had the worst record in the NBA last season, will likely start Stephen Curry, Oubre Jr., Andrew Wiggins, Draymond Green and rookie James Wiseman in 2020-21. Golden State drafted Wiseman out of Memphis with the second overall pick in the 2020 draft.

Even though Curry and Green are champions and Wiggins and Oubre Jr. have All-Star potential, the Warriors will have a hard time entering the title picture next season without Thompson, who is one of the best shooters and defenders in the NBA.

Since entering the league in 2011, Klay has compiled averages of 19.5 points, 3.5 rebounds and 2.3 assists while shooting 41.9 percent from beyond the arc. He has made five All-Star teams and helped the Warriors win three titles.
