Mannigham was activated to the 53-man roster this week. He suffered a knee injury last December. On Thursday, San Francisco offensive coordinator Greg Roman was non-committal about the immediate plan for Manningham. Roman said Manningham was “day-to-day.” On Wednesday, Manningham said he was planning to play Sunday.
The 49ers badly need production from their No. 2 receiver, and Manningham could step into that spot.
The only non-healthy scratch is expected to be rookie receiver Quinton Patton. He is coming off a broken foot. One of the healthy scratches is likely going to be rookie defensive lineman Tank Carradine, who suffered a torn ACL last year at Florida State. Carradine said Thursday he will likely not be active right away, but he expects to play soon.
