49ers placed RB Marcus Lattimore (knee) on injured reserve, ending his season.
Lattimore practiced the last three weeks while on the NFI list and hasn't had any setbacks in his recovery from major knee surgery, but was never expected to be activated this season. With Frank Gore entering a contract-year in 2014, he remains a strong "hold" in Dynasty leagues and will take part fully in the 49ers’ offseason program. "If I had to play, I would," Lattimore told CSN Bay Area. "Without question, if they needed me. But they don’t need me right now. Going into next year, I can’t wait."
Cowboys ILB Sean Lee (hamstring) is listed as probable for Week 14.
Lee practiced in full this week and will return after missing just three games. It's a massive boost for the Cowboys, who will be getting back their best linebacker as they attempt to stay in first place in the NFC East. Lee has 93 tackles, four interceptions and one fumble recovery in 10 games this season.
Brandon Marshall (quad) was a full participant in Saturday's practice and is listed as questionable for Week 14.
Marshall missed practice earlier in the week for rest purposes, but his status was never in doubt for Monday night's game. Rotoworld ranks Marshall as the No. 4 overall wideout for Week 14.
Titans promoted WR Michael Preston from the practice squad.
It's a sign that Damian Williams (questionable, hip) might not be ready to return. Preston has appeared in four games this season and will contribute on special teams if active. OL Kevin Matthews was waived in a corresponding move.
Lions waived WR/KR Micheal Spurlock.
Spurlock is no longer needed after being replaced on kick returns by Jeremy Ross. With Darius Slay (knee) ruled out for Week 14, the Lions have promoted CB Chris Greenwood off their practice squad.
Steelers activated TE Matt Spaeth (foot) from injured reserve/designated to return.
Spaeth resumed practicing last month and has been medically cleared to return from his Lisfranc injury. A strict blocking tight end, he'll provide depth in a reserve role behind Heath Miller.
Raiders placed FS Usama Young on injured reserve with a neck injury, ending his season.
Young suffered the injury in Week 13 and would have been a long shot to return this season. A rotational safety, he finishes 2013 with 26 tackles, 2.5 sacks, and one interception. The Raiders have just two healthy safeties on their active roster, so it's a sign Tyvon Branch (fibula/ankle) could return next week.
Ravens waived RB Bernard Scott.
The move clears a spot for Dennis Pitta's return to the active roster. Scott was signed in Week 8 after being released by the Bengals and has yet to appear in a game this season.
