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

The 6-foot-11, 230-pound Muscala averaged 14.6 points and led the ACB League in Spain with 7.8 rebounds per game.

The Hawks lost All-Star center Al Horford to a season-ending surgery for his torn right pectoral muscle in December. Two more centers, Pero Antic (stress fracture in his right ankle) and Gustavo Ayon (right shoulder) also are injured.

The Hawks held NBA rights to Muscala as he played for Blusens Monbus Obradoiro of the ACB League in Spain. Details of the buyout agreement were not released.

The Hawks released center Dexter Pittman, who signed a 10-day contract on Saturday, to open a roster spot for Muscala.
