Rick Fox has filed for divorce from Vanessa Williams.

The two have been married for five years and have a 4-year-old daughter.

"They are both extremely devoted parents, so the most important thing to them right now is the welfare of their child," a spokesperson for Rick Fox said.  "They are committed to working out what's best for her."

Fox is 35 and may retire due to injuries, after being traded from the Los Angeles Lakes to the Boston Celtics.  

The couple had been separated.
