Dre Greenlaw Suspended One Game For Sideline Headbutt

San Francisco 49ers linebacker Dre Greenlaw has been suspended one game without pay for unsportsmanlike conduct after headbutting helmetless Seahawks linebacker Ernest Jones IV during a sideline altercation. Head coach Kyle Shanahan expressed disappointment over the league's decision. Greenlaw, who logged 37 tackles this season, is appealing the discipline and faces missing a crucial matchup against Washington.
