Ailing 49ers WR Ricky Pearsall (knee) active vs. Seahawks

49ers receiver Ricky Pearsall is on San Francisco's active roster for Saturday night's NFC divisional round matchup against the host Seattle Seahawks.

Pearsall, who is dealing with a right knee injury, missed last weekend's NFC wild-card victory over the Philadelphia Eagles. He injured the knee against the Tennessee Titans on Dec. 14 and has seen action in just one game since being hurt.

Pearsall, a second-year pro, caught 36 passes for 528 yards and no touchdowns in nine games this season and has battled with injuries throughout the season.

Seahawks quarterback Sam Darnold participated in pregame warmups and didn't seem greatly bothered by his oblique injury. Darnold "felt a little something" on his left side while throwing Thursday.

Drew Lock is Seattle's backup quarterback.

The Seahawks' inactives are quarterback Jalen Milroe, offensive linemen Josh Jones, Bryce Cabeldue and Mason Richman, defensive end Rylie Mills and linebacker Jared Ivey.

San Francisco's inactives are running back Isaac Guerendo, receiver Jordan Watkins, offensive lineman Brandon Parker, defensive linemen Robert Beal Jr., Kevin Givens and Sebastian Valdez and safety Ji-Ayir Brown (hamstring). Brown was injured in the second quarter against the Eagles.
