49ers place Hassan Ridgeway on IR, announce other roster moves ahead of Seahawks game

The San Francisco 49ers have announced the following roster moves ahead of tonight's game against the Seattle Seahawks at Lumen Field.

Promoted from the practice squad to the active roster:

• DL Akeem Spence

Placed on injured reserve:

• DL Hassan Ridgeway

Elevated from the practice squad:

• CB Janoris Jenkins
• WR Willie Snead IV

Ridgeway sustained a pectoral injury during Week 13's matchup against the Miami Dolphins and was expected to miss six to eight weeks. That would have pushed his potential return toward the end of the postseason, at the earliest.

San Francisco ruled out defensive lineman Kevin Givens (knee) and defensive backs Samuel Womack (concussion) and Tarvarius Moore (knee) against Seattle. Defensive back Donate Johnson (knee) was placed on the practice squad injured reserve list this week. Defensive lineman Kerry Hyder (ankle) is listed as "questionable."

The 49ers and Seahawks kick off tonight at 5:15 p.m. PT. San Francisco can clinch the NFC West title with a win, ensuring the team opens the playoffs at home.
