Dre Greenlaw's Suspension Appeal Denied for Helmet Headbutt

San Francisco 49ers linebacker Dre Greenlaw will miss Monday night's game against the Washington Commanders after the NFL denied his appeal of a one-game suspension. Greenlaw was ejected from Sunday's Week 5 game against the Seattle Seahawks for using his helmet to headbutt Ernest Jones IV, who was not wearing a helmet. This marks Greenlaw's second career suspension. Rookie Jaden Dugger is expected to start in his absence on Monday night.
