Hawks center Gustavo Ayon had season-ending surgery on his right shoulder, the Hawks announced Friday.
Ayon has missed the past five games with the injury suffered Feb. 18 against the Pacers. He also missed the first eight games of the season with a right shoulder suffered during the exhibition season.
Ayon appeared in 26 games this season, including 14 starts, and averaged 4.3 points and 4.8 rebounds in 16.5 minutes.
The surgery was performed at Piedmont Hospital by Dr. Xavier Duralde and accompanied by Hawks team physician Dr. Michael Bernot from the Peachtree Orthopaedic Clinic, according the the team.
Ayon will now undergo a period of rest, treatment and rehabilitation.
The Hawks signed second-round pick Mike Muscala Thursday after working out a buyout agreement with his Spanish League team.
The Hawks signed Ayon to a one-year $1.5 million contract as a free agent this summer.
