“The NFL has been an amazing page in this chapter of my life,” Williams said in a statement posted on the Ravens’ website and on the site of the University of Texas where he once starred.
“I pray that all successive adventures offer me the same potential for growth, success and most importantly, fun.”Williams, whose career stats also include 342 pass receptions for 2,606 yards and eight touchdowns, has retired before.
He first retired in 2004, but returned to the Miami Dolphins for the 2005 season. He later said in a television interview that he retired to avoid the embarrassment of seeing a failed drug test made public.But Williams was suspended for all of the 2006 NFL season after another failed test for marijuana.
He spent the season playing in the Canadian Football League before returning to the Dolphins in 2007. Just a fortnight ago Williams had said he expected to return to the Ravens for the final year of his two-year contract.Instead he departs as one of 26 players in NFL history to top 10,000 career rushing yards.
