Boxing legend Muhammad Ali has been released from the hospital after being treated for a urinary tract infection, media reports said Wednesday.

Ali, 72, was admitted more than two weeks ago with what was then thought to be pneumonia.

But doctors ultimately determined he had a severe urinary tract infection, and he was released Tuesday night, the Courier-Journal newspaper reported, quoting Ali spokesman Bob Gunnell.

Ali is a three time world heavy-weight champion and Olympic gold medalist. He has suffered from Parkinson's disease since the 1980s.

"The boxing legend has fully recovered and is now at his home. Ali looks forward to celebrating his upcoming 73rd birthday on January 17th with his family and friends," Gunnell said in a statement, according to www.allsports.com.

"The Ali family greatly appreciates the outpouring of support and continued well wishes. They also want to thank the team of doctors and nurses for their exceptional care."
