Hearing officer James Thrash upheld 49ers LB Dre Greenlaw’s one-game suspension.

Greenlaw was suspended after he was ejected for headbutting Seahawks LB Ernest Jones during a sideline scuffle in the 49ers’ Week 5 win over the Seahawks. He appealed the suspension, but it has been upheld by hearing officer James Thrash. Greenlaw will miss Week 6 and is in line to return against the Falcons in Week 7.
