Atlanta Hawks en Chicago Bulls

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).

Shoulder

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.

Knee

Collins' 2025-26 season was cut short after he underwent surgery in February due to a sprained toe on his right foot. It's unclear if the current soft tissue injury is related to the toe, but the big man's status will be worth monitoring ahead of Chicago's preseason opener against Phoenix on Wednesday, Oct. 7. If he's forced to miss time to start the regular season, Jalen Smith would have a much clearer path to playing time behind Nic Claxton.
