Donte Stallworth, the Cleveland Browns receiver who struck and killed a man while driving drunk, has been suspended without pay for the 2009 season, the NFL announced Thursday.

NFL Commissioner Roger Goodell imposed the suspension because Stallworth violated the league's policies on substance abuse and personal conduct.

Stallworth, who may not participate in any team activity this season, will be reinstated after the Super Bowl in February. His case sparked public outrage because, after pleading guilty to drunk driving and manslaughter in Florida, he was sentenced to just 30 days in jail -- and was released after serving 24.
