Los Angeles Lakers center Deandre Ayton has been ruled out for Sunday's game against the Miami Heat due to back spasms, despite initially being listed as probable. Lakers head coach JJ Redick revealed that Ayton was still dealing with back tightness and spasms, prompting the team to exercise caution. Ayton, who expressed optimism about playing, was downgraded from questionable just hours before the game. In the recent game against the Memphis Grizzlies, Ayton departed at halftime due to back spasms but returned for the fourth quarter, though he did not re-enter the game. Lakers coach JJ Redick explained that Ayton chose not to risk further injury, and the team managed to secure a 117-112 victory without him. Redick also praised Ayton for his patience and efficiency this season, noting his limited touches but effective play. Ayton's early season performance has been mixed, with averages of 14.8 points, 7.8 rebounds, and solid shooting percentages. Meanwhile, Luka Doncic led the Lakers with a dominant 44-point game, marking his third 40+ point outing this season. The Lakers plan to start Jaxson Hayes in Ayton's absence against the Heat, with Jarred Vanderbilt and Christian Koloko also available for backup roles.
