Update: CBSsports.com is reporting that Baltimore Ravens WR Derrick Mason missed practice again Thursday for the second straight day with ankle injury. His status for next week against the New Orleans Saints is uncertain.

Fantasy Impact: Mason has been hot in his last few weeks, scoring five touchdowns in the past six games. As defenses are paying more attention to WR Anquan Boldin, Mason has been able to break out and put up numbers. If healthy, he should be considered a number two or three receiver in terms of fantasy.

Update: CBSsports.com is reporting that Minnesota Vikings WR Percy Harvin is finally back at practice after missing some time with migraine headaches. Harvin has been battling the migraines all season and has missed the past two games.

Fantasy Impact: If everything goes smooth, Harvin should be back on the field next week. However, he shouldn't be started due to the Vikings quarterback situation. Sit him this week.

Update: CBSsports.com is reporting that Minnesota Vikings RB Adrian Peterson sat out practice Thursday with an ankle injury. He sustained the injury in week 13 but hasn't missed any playing time. His status for next week is uncertain.

Fantasy Impact: Peterson will most likely play next week, but he will be ging up against the number two rush defense in the NFL on Monday. Fantasy owners with a different running back with a better matchup may be wise to start them since he only managed to post 26 yards last week against the New York Giants on the injured ankle.

Update: CBSsports.com is reporting that Minnesota Vikings QB Brett Favre still isn't close to returning to action. He spoke with the media on Thursday and said that he still has numbness in his hand and that he is nowhere close to ready to playing.

Fantasy Impact: The Vikings quarterbacks are all banged up right now. Favre is the best chance they have to win but it looks like his age is finally catching up with him. He has no fantasy value at this point since he hasn't been playing well at all this year.

Update: Profootballtalk.com is reporting that the Vikings are expected to place QB Tavaris Jackson on IR, ending his season. Jackson suffered a turf toe injury in last weekend's start and had to be taken out of the game at one point.

Fantasy Impact: Patrick Ramsey has been signed as a backup option at the position as it looks like rookie Joe Webb will start. Jackson had his only start of the season cut short because of his injury. It will be an interesting offseason for Jackson as the Vikings go into it with a gaping hole at the QB position if Favre's career is over.

Update: Rotoworld.com is reporting that Browns coach Eric Mangini has named Colt McCoy the starting QB for the rest of the season. McCoy has missed the past three weeks with a high ankle sprain. He took over the starting role back in week 6.

Fantasy Impact: The Browns are running out of options at QB. McCoy won't be 100%, but he will probably give the team the best chance of winning the game against the Bengals. The Bengals have had a miserable season this year. Expect the Browns to go with the run as usual and run the offense through Peyton Hillis.

Update: Rotoworld.com is reporting that the Vikings are looking more likely to start rookie Joe Webb this weekend at Quarterback. Brett Favre, who's games started streak ended last week, might not ever play again. And Tavaris Jackson has a turf toe injury and he's very questionable this week.

Fantasy Impact: Joe Webb has been battling a hamstring injury for the past couple weeks, but should be ready in case he would have to start Monday Night. Webb, a 6th round pick from UAB, was a WR in college. In some fantasy leagues his is listed as a WR, so Webb may have some value this week as a WR if he starts.
