Greenlaw was sidelined in Week 6 against the Cleveland Browns due to a hamstring injury. His return to the lineup is anticipated for tonight's game. The 49ers will officially announce their inactive players 90 minutes ahead of kickoff.
Running back Christian McCaffrey, the other player labeled as "questionable," is also slated to play despite dealing with a "slight" oblique tear.
However, tackle Trent Williams, listed as "doubtful," is unlikely to take the field due to an ankle injury.
