Ace Bailey has been balling out for the Utah Jazz in their first two preseason games. The No. 5 pick of the 2025 NBA draft seems to be acclimating well in Salt Lake City after initial reluctance to be there. He eventually fired his agent before the start of training camp.Bailey made his preseason debut against Kevin Durant and the Houston Rockets. He had an impressive game, finishing with 25 points, six rebounds, three assists, two steals and one block in 31 minutes. He went 11-for-16 and made two 3-point shots.In their next game against the San Antonio Spurs, Bailey put up another good game with 20 points, seven rebounds, one assist and two steals. He started both contests at shooting guard, as well as Monday's game against the Dallas Mavericks. So how did Ace Bailey perform against the Dallas Mavericks? The Rutgers product finished with just three points, one rebound and one steal in nearly 11 minutes of action in the first half. He didn't play in the second half after getting ruled out with a knee injury. Bailey struggled with his shot in the first two quarters, going 1-for-5, but he made one shot from beyond the arc. He also committed two personal fouls that limited him in the first period.Here are Ace Bailey's stats for the game.PlayersPTSREBASTSTLBLKTOPFMINFG3PTFT+/-Ace Bailey310100210:441-51-20-0-13What happened to Ace Bailey?What happened to Ace Bailey?

Ryan Miller @millerjryanLINKAce Bailey (bilateral knee soreness) will not return. He went to the locker room near the end of the first half.In Bailey's absence, Jazz coach Will Hardy went with Cody Williams and Brice Sensebaugh. Williams had 13 points, three rebounds, two assists, one steal and two blocks, but he shot just 5-for-14. Sensebaugh finished with 16 points and three rebounds, going 6-for-10 and knocking down three 3-point shots. It wasn't enough, as the Dallas Mavericks earned the 114-101 win. Anthony Davis led the way with 25 points, six rebounds, two assists, two steals and two blocks. Cooper Flagg started at point guard, putting up 11 points, seven boards, two steals and two blocks. The Jazz have one more preseason game left on Oct. 16 at home against the Portland Trail Blazers. It will be interesting to see if Bailey gets cleared to play before the start of the regular season.
