Update: NFL.com is reporting that Tennesee Titans QB Kerry Collins could start next week against the Jacksonville Jaguars. Collins has missed the past two games with a strained calf muscle. The Titans have also lost starting QB Vince Young for the year with a thumb injury.

Fantasy Impact: The Titans are on a four game losing streak, partly due to the quarterback situation. Even RB Chris Johnson, arguably the best runnning back in the NFL, has suffered by being held to under ten yards rushing last week. Collins is needed for the Titans to get back on track, but even if he does play he isn't a reliable fantasy option at quarterback.

Update: CBSsports.com is reporting that Minnesota Vikings Interim Head Coach Leslie Frazier is unsure if RB Adrian Peterson will be able to play next week. Peterson suffered an ankle sprain last week. However, an ESPN report earlier in the week said that Peterson is expected to play.

Fantasy Impact: If he is good to go next week, Peterson will have a great matchup against the Buffalo Bills. However, if not, owners should grab RB Toby Gerhart from free agency to fill in for Peterson. Either way, grab Gerhart now and drop him later if Peterson is ready for next week.

Update: CBSsports.com is reporting that Oakland Raiders QB Bruce Gradkowski seperated his throwing shoulder in Sunday's loss against the Miami Dolphins. This is the second time this year that he seperated the shoulder and it is expected that he will miss the remainder of the season. QB Jason Campbell will start at quarterback in his absence.

Fantasy Impact: The Raiders have been playing better this year than in recent years, but neither Gradkowski or Campbell are good starting fantasy quarterbacks. Look for help elsewhere as fantasy leagues move towards the playoffs.

Update: CBSsports.com is reporting that new England Patriots QB Tom Brady sat out practice Tuesday with a foot issue. Brady has been on in the injury report for the past few weeks, but hasn't missed any playing time.

Fantasy Impact: If Brady is having problems with his foot, he certainly didn't play like it last week against the Detroit Lions. Brady should be fine for week 13 against the New York Jets. Obviously, he is arguably the best quarterback in the NFL and should be in all starting fantasy lineups.

Update: ESPN.com is reporting that Pittsburgh Steelers QB Ben Roethlisberger is in a walking boot after suffering a sprained foot last week. However, he is still expected to play next week against the Baltimore Ravens.

Fantasy Impact: Roethlisberger did not leave the game even after suffering the injury, which is a good sign that it isn't too serious. But to be safe monitor his status throughout the week and make sure he is good to go in week 13.

Update: ESPN.com is reporting that San Francisco 49ers RB Frank Gore will miss the remainder of the 2010 season with a broken hip. Gore suffered the injury Monday night against the Arizona Cardinals. RB Brian Westbrook will start in place of Gore.

Fantasy Impact: Gore owners will need to drop him as soon as possible and pick up Westbrook, who rushed for 136 yards and a touchdown while filling in for Gore. Westbrook is aging, but he was a huge part of the Eagles offense while in Philadelphia and still can be productive when given the opportunity.
