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 signed CB Chris Greenwood off their practice squad in a corresponding move.
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.
Chargers activated OLB Melvin Ingram (ACL surgery) from the reserve/PUP list.
Ingram has made an impressive recovery from his mid-May ACL tear and will play in Sunday's game against the Giants. It's a massive upgrade to a Chargers defense that's lost both Dwight Freeney and Larry English to injured reserve. Ingram will likely be eased in as a situational pass rusher before reclaiming his starting job. LB Adrian Robinson was waived to make room on the 53-man roster.
Ravens activated TE Dennis Pitta (hip) from the injured reserve/designated to return.
Pitta has been practicing the last three weeks and is expected to be on a limited snap count in his first game back. His return has the potential to improve a Ravens offense that lacks a true possession receiver, though his exact role remains to be seen coming off a major injury. Pitta is worth stashing as a TE2 in re-draft formats, but isn't a realistic fantasy option for Week 14.
Carson Palmer (elbow, questionable) took all the snaps at Saturday's walkthrough and is expected to start in Week 14 against the Rams.
Palmer was limited in practice all week with an elbow injury, but is on track to play Sunday in a must-win game for Arizona. Despite his recent hot streak, he won't be a recommended streaming option in standard fantasy leagues at less than 100 percent. Palmer is averaging 345 passing yards and has seven touchdowns over his last three games. Rotoworld ranks him as the No. 17 quarterback for Week 14.
Lions CB Darius Slay has been diagnosed with a torn meniscus in his knee.
Slay suffered the injury in Thursday's practice and is listed as doubtful for Week 14. The Lions are calling him "week to week" for now, but Slay underwent knee surgery this offseason for a similar issue and could be shut down for the final four games. After sitting out Detroit's Thanksgiving victory over the Packers, Chris Houston (questionable, ankle) is expected to return this week and will start opposite Rashean Mathis.
