Boxing legend Muhammad Ali was released from hospital on Friday after receiving treatment for a severe urinary tract infection, a family spokesman said.

Bob Gunnell of Louisville-based Boxcar PR said Ali was looking forward to celebrating his 73rd birthday on Saturday at home with family and friends.

“The Ali family greatly appreciates the outpouring of support and continued well wishes,” Gunnell said.

Ali’s hospital stay of several days this week was his second in the last month.

The three-time former heavyweight world champ was released from hospital on January 7 after a two-week stay for what was then thought to be pneumonia.

But doctors ultimately determined he had a urinary tract infection.

Ali, an Olympic gold medallist, has suffered from Parkinson’s disease since the 1980s.
