Hawks' Ayon has season-ending shoulder surgery

ATLANTA -- Hawks center Gustavo Ayon will miss the remainder of the season following surgery on his right shoulder.

Ayon started 14 games, most coming after injuries to All-Star center Al Horford and top backup Pero Antic. Ayon's surgery on Friday was performed in Atlanta by Dr. Xavier Duralde and Hawks physician Dr. Michael Bernot.

Ayon averaged 4.3 points and 4.8 rebounds in 26 games.

Elton Brand has started the last five games following Ayon's injury.

The Hawks signed center Mike Muscala, a 2013 second-round draft pick, on Thursday after completing the buyout of his Spanish League contract.
