Niners LB Greenlaw's appeal rejected, will serve 1-game ban vs. Commanders

San Francisco 49ers linebacker Dre Greenlaw 's appeal of a one-game suspension was denied by the NFL on Tuesday, and he will miss the team's Monday night game against the Washington Commanders . Greenlaw was suspended without pay by the league following an unsportsmanlike conduct penalty in Sunday's win against the Seattle Seahawks . With 6:30 left in the first half of that game, Greenlaw hit Seattle quarterback Sam Darnold late and out of bounds, then was involved in a skirmish with Seahawks linebacker Ernest Jones IV in which he head-butted Jones, who was not wearing a helmet.
