Kelly's spokeswoman, Tricia Cavalier, said he was released from the hospital Monday, three days after the operation.
Kelly's wife, Jill, posted a note on her Twitter account Wednesday, saying "there's a long road ahead," but doctors are pleased with her husband's recovery. She said the next step is awaiting results of bone tests.
Dave Jickster, who works for Buffalo's 97-Rock, said Kelly's spirits are good and "he's got the right attitude." Jickster visited Kelly to present him an over-sized "Get Well" card signed by numerous supporters.
Jickster released photos showing Kelly flashing a thumbs-up sign posing next to the card.
