Ali out of hospital, at home before birthday

Muhammad Ali is out of the hospital again after continued treatment for a severe urinary tract infection and back at home, resting up before he turns 73 on Saturday.

According to family spokesman Bob Gunnell, Ali plans to watch the University of Louisville's basketball game against Duke while celebrating his birthday with family and friends.

The boxing legend's family, Gunnell said, "greatly appreciates the outpouring of support and continued well wishes."

Ali was hospitalized Thursday following a previous 17-day stint for the infection over the holidays. His return was for follow-up care, Gunnell said, with Friday marking his planned release.

The Louisville native and former heavyweight champion has suffered from Parkinson's disease for decades, and though his health has declined over the years, he's continued to appear publicly, most recently at his grandson's state championship football game last month in Las Vegas.
