Fantasy Football: Five Key Injury Updates for Week 1

Football is finally here. The grass fields are perfectly trimmed for precision. The popcorn machines are pumping, the beer is brewing, and the hot dog vending machines are sending that aroma throughout the streets to give that football atmosphere.

This day brings excitement to most, but inflicts confusion on others. The complication that football may bring to fantasy owners is injuries.

I'm here today to give you the recent updates on injuries that may affect your fantasy league. I've done some research on five key players that may be owned in every fantasy league.

From all of us at Bleacher Report, enjoy a happy Week 1!

5. Brett Favre, QB, Minnesota Vikings: Probable

Brett Favre completed a full practice and looks ready for tonight's game against the defending champion New Orleans Saints.

The only thing to keep in mind with Favre is that his ankle is extremely delicate at the moment. For now he's listed as probable.

Let's hope he makes it through the first half.

4. Marques Colston, WR, New Orleans Saints: Probable

Marques Colston is listed as probable. He completed a full practice and looks to be the starter for tonight's game against the Minnesota Vikings.

Colston has experienced some problems with his kidneys and is being watched by doctors and trainers as he completes every play.

3. Chris Wells, RB, Arizona Cardinals: Questionable

Chris Wells is questionable for Week 1. Doctors have been monitoring the progress with his knee and are finding that his recovery is slow but advancing.

My football sense says that he dresses but doesn't get more than five attempts rushing. Wells is the future at running back for the Cardinals; with that said, my best bet is that he may even be out for Week 1.

2. Knowshon Moreno, RB, Denver Broncos: Probable

Knowshon Moreno completed a full practice and is making some positive progress. His hamstring seems to have healed, and he looks good to go for Week 1 of the NFL season.

Moreno was once listed as questionable in previous weeks. My synopsis says that he's probable.

1. Donovan McNabb, QB, Washington Redskins: Probable

The Washington Redskins received a scare when Donovan McNabb was helped off the field when he injured his ankle.

Many had him out for Week 1 of the regular season. Well, McNabb's sprained ankle looks like it has healed.

McNabb has a lot to prove this year after being traded away from the Philadelphia Eagles. I could never see him missing out the season opener. If everything stays the same for McNabb, he will be the starter against the Dallas Cowboys.
