Atlanta Hawks at Dallas Mavericks

Gueye will be re-evaluated by medical staff in 3-to-4 months, which means he'll miss all of training camp and preseason and likely the start of the 2026-27 regular season. It's a brutal blow for the fourth-year big man, given that the Hawks used the No. 23 overall pick of the 2026 NBA Draft to select St. John's product Zuby Ejiofor. Gueye's absence means Ejiofor will have more opportunities in the preseason, and the rookie could establish a key role off the bench behind Onyeka Okongwu and projected backup center Jock Landale (ankle).

Dennis will miss a third consecutive contest due to a right Achilles issue. He appeared in just one Las Vegas Summer League game, posting 10 points, three assists, three steals and two rebounds in 16 minutes during the July 9 win over the Spurs.

A hip injury cost Gilbert his final three games in Las Vegas. In his one appearance for the Hawks at Summer League, he finished with 10 points, five rebounds, five assists and two steals in 20 minutes off the bench.

Head coach Dusty May didn't elaborate, only stating Aldama is dealing with a "nagging injury." The 2021 No. 30 overall pick had spent his entire career in Memphis before being traded to Dallas in July of 2026. In 278 regular-season games, including 82 starts, he averaged 10.4 points, 5.4 rebounds and 2.1 assists over 23.4 minutes per contest. His shooting acumen will allow the Mavericks to stretch the floor, and his versatility enables him to man multiple positions while playing various roles. Aldama underwent knee surgery in March, and while it's unknown if that's still a concern, fantasy managers should continue monitoring his health throughout training camp.

Irving missed the entire 2025-26 season while recovering from surgery to repair a torn ACL in his left knee, but he has been participating in pickup games during his ramp-up process. The 34-year-old last played in 2024-25, when he averaged 24.7 points, 4.8 rebounds, 4.6 assists and 1.3 steals in 36.1 minutes across 50 regular-season appearances. Ujiri's comments provide another positive sign that Irving is closing in on his return, though Dallas has yet to announce a definitive timeline.

Ujiri noted that Lively has progressed to shooting and is working toward running on the court, though Dallas intends to remain patient with the 22-year-old. Lively underwent right foot surgery in December after appearing in just seven regular-season games in 2025-26, averaging 4.3 points, 5.3 rebounds, 1.9 assists and 1.6 blocks in 16.4 minutes per game. He has yet to be cleared for training camp, and his status for the beginning of the regular season remains uncertain.
