Former WBC light heavyweight champion Oleksandr Gvozdyk was released from a Philadelphia hospital Sunday morning.

Ukraine’s Gvozdyk spent two nights at Temple University Hospital after suffering a concussion during his 10th-round, technical-knockout loss to Artur Beterbiev on Friday night at Temple’s Liacouras Center. Teddy Atlas, Gvozdyk’s trainer, told ESPN.com on Sunday morning that Gvozdyk was held for observation following a physically taxing fight in which he was knocked down three times in the 10th round.

“All is clear,” Atlas said. “No [brain] bleed or anything. Thank God, just a minor concussion from the hits to the back of the head they said, but we needed to be sure.”

Atlas accompanied Gvozdyk from the venue to the nearby hospital in an ambulance early Saturday morning. Gvozdyk, 32, underwent a battery of tests because he complained of pain in the back of his head.

As a precautionary measure, the Pennsylvania Athletic Commission will place Gvozdyk on a medical suspension that’ll require him to undergo a full battery of tests before he can fight again.

Gvozdyk (17-1, 14 KOs) was winning their 12-round, 175-pound title unification fight on two of three scorecards when referee Gary Rosato stopped it at 2:49 of the 10th round. Rosato halted the action as soon as Gvozdyk went to a knee for the third time in that round.

Judges John McKaie (87-84) and Ron McNair (86-85) had Gvozdyk in front following nine rounds. Judge John Poturaj favored Beterbiev, 87-83, entering the 10th round.

Gvozdyk took a lot of power punches from the hard-hitting Beterbiev in the ninth and 10th rounds, however. CompuBox credited Beterbiev with a 49-8 edge over Gvozdyk in power punches in those two rounds.

Russia’s Beterbiev (15-0, 15 KOs) defended his IBF belt and won the WBC crown from Gvozdyk in a main event ESPN televised.

Ten months ago, Gvozdyk won the WBC championship by knocking out Quebec’s Adonis Stevenson in the 11th round at Videotron Centre in Quebec City, Canada. Stevenson suffered a brain injury in that defeat, underwent emergency surgery and was placed in a medically induced coma.

The 42-year-old Stevenson since has recovered. He learned how to talk and walk again, and is considered relatively healthy.
