Fantasy Football Waiver Wire: QB | RB | WR | TE | PK | DT

If you are serious about winning your fantasy league football championship, stay on top of your fantasy football team throughout the year.

Each week during the NFL fantasy football season, KFFL brings you its Fantasy Football Waiver Wire, which breaks down players to pick up. Be aggressive when picking up fantasy football free agents. Even if you do not need a player, you can tuck him away for depth or block others from adding him to their fantasy football team.

Fantasy football free agents: One-week plays

The following fantasy football pickups are for those who need injury or bye week replacements. They are not players you immediately acquire - unless your team is in dire straights. Some have, however, shown some life and should be followed in case they materialize as options beyond their temporary use.

Be on the Ball this week

Lance Ball, Denver Broncos (66 percent)

Willis McGahee (leg) is iffy for Week 16, and even if he plays, Ball should see significant work. Ball toted the rock 11 times for 64 yards and a touchdown Sunday along with two catches for 41 yards. The Buffalo Bills, Denver's opponent on Christmas weekend, have been generous with presents to opposing carriers over the last four weeks: 170.0 rushing yards, 27.3 receiving yards and 1.00 total touchdowns per game.

Kahlil Bell, Chicago Bears (85 percent)

Bell has taken on a strong role since Matt Forte (knee) was sidelined, catching 10 passes for 67 yards and rushing 22 times for 105 yards over the last two weeks. He's the better PPR option than Marion Barber III and should continue to flex his reception muscles against the Green Bay Packers in Week 16. Green Bay has allowed 102.0 rushing yards, 9.25 catches, 66.3 receiving yards and one total touchdown per contest to the position since Week 11.

NEW - Sammy Morris, Dallas Cowboys (96 percent)

Felix Jones - surprise - is hurt again; he's feeling hamstring tightness and missed practice Tuesday and Wednesday. Dallas says it's precautionary, but you can never be too prepared, especially in a championship week. Morris and Chauncey Washington would probably split reps if Jones were to miss the game or be limited.

Jason Garrett pointed to Morris, who gained 53 yards on 12 carries in running out the clock in Week 15, as the logical starter if Jones can't go. He'd be more helpful because of his pass-blocking skills for Dallas' throw-first offense. Even when keeping it on the ground, he'll be facing a Philadelphia Eagles defense that has allowed 111.5 rushing yards, 4.25 receptions, 29.0 receiving yards and one offensive score per game to the position since Week 11.
