Phoenix Suns superstar Devin Booker was added to the All-Star roster last week, but now he will have to bow out due to an apparent left knee sprain.

Booker was going to replace Anthony Davis, but he had to be substituted by Utah Jazz point guard Mike Conley, according to Shams Charania of The Athletic.

Booker and the Suns were wrapping up their first half of the season against the Golden State Warriors on Thursday night when he appeared to have hurt his knee in the first quarter. From a closer look, it looks like he bumped knees with Dubs' forward Kent Bazemore and fell to the floor in agony. He remained in the game and finished with 16 points in 29 minutes.

Here is the exact play that he got hurt on.

Devin Booker has led the Suns to the second-best record in the Western Conference, just 2.5 games behind the league-leading Jazz. Booker's numbers are All-Star worthy, with a team-leading 24.9 points per game. He was selected as a reserve by Team Durant during Wednesday's All-Star Draft.

It's also worth noting that Conley will replace Booker in the 3-point contest. In 14 seasons in the NBA, this will be Conley's first appearance playing in the All-Star game.

Booker was initially left off the All-Star roster, which prompted LeBron James to chime on and the fact that he's often overlooked. Booker is technically a two-time All-Star despite not playing in this weekend's festivities.
