The San Francisco 49ers will play the rest of the season without receiver Mario Manningham, meaning 35-year-old Randy Moss will start Sunday against the 5-10 Arizona Cardinals.

Manningham suffered torn ligaments in his left knee during Sunday night's 42-13 loss to the Seattle Seahawks. Comcast SportsNet Bay Area reported Tuesday that Manningham is scheduled for season-ending surgery and might not be ready for the start of next year's training camp.

Moss has had a positive presence but not too many receptions in his return from a one-season hiatus. He has averaged 1.7 catches per game for the 49ers (10-4-1). A potential Hall of Famer, Moss has produced one of the great careers in NFL history, but he's not about to turn the clock back five years. He hasn't caught more than three passes in a game since Week 1.

Bengals get wideout

The Cincinnati Bengals have acquired wide receiver Dane Sanzenbacher on waivers from the Chicago Bears and placed first-round draft pick cornerback Dre Kirkpatrick on injured reserve. Sanzenbacher was released earlier this week by the Bears and was picked up Tuesday by the Bengals.
