THREE UP, THREE DOWN

UP: Brandon Jackson, RB, Green Bay:
If he's available, expect Jackson's name to light up waiver wires this week. Ryan Grant, the starter in Green Bay, left Sunday's game with a 'sprained thumb,' and Jackson stepped in with 80 yards on 11 carries. The second-year pro from Nebraska is great insurance for Grant owners about to begin the postseason.

UP: Cadillac Williams, RB, Tampa Bay:
Another insurance policy. Starter Earnest Graham is out for the season, and mainstay Warrick Dunn received the bulk of the carries last weekend against New Orleans, but Williams -- who returned against the Saints after missing the previous 14 months with a brutal knee injury -- had his number called on the goal line and delivered an 8-yard touchdown run.

UP: Davone Bess, WR, Miami:
Starting in place of the injured Greg Camarillo, Bess produced six catches for 84 yards against St. Louis. Bess is not a No. 1 or 2 fantasy option, but he can provide depth during the playoffs. In addition, the rookie from Hawaii has some favorable matchups on the horizon. The Dolphins' next three opponents are Buffalo, San Francisco, and Kansas City.

DOWN: Clinton Portis, RB, Washington:
Portis is battling nagging injuries and had to be repeatedly pulled from last weekend's game against the Giants. One of the NFL's best backs throughout the season, Portis is in the middle of two straight brutal matchups: the Giants and this weekend's opponent, Baltimore. If you own Portis, try to get your hands on his backup, Ladell Betts.

DOWN: Kellen Winslow, TE, Cleveland:
Winslow banged up his ankle against the Colts (he also has a sprained shoulder) and he's now going to be catching passes from his third starting quarterback of the season. Career backup Ken Dorsey takes over now that Brady Quinn and Derek Anderson are out for the season.

DOWN: Marion Barber, RB, Dallas:
Another premier back who is banged up (toe) and has a difficult matchup: The Cowboys are heading into Pittsburgh to face the Steelers and their top-ranked defense.
