Eli Manning: 10 Most Important NFL Preseason Injuries To Monitor

The preseason has already produced its share of casualties, including Eli Manning and Larry Fitzgerald.  In the meantime, there are plenty of players looking to make up for lost time as they return to practice.

One of those players is Percy Harvin, who missed the first two weeks of Vikings' training camp while dealing with migraines.  After collapsing at practice Thursday, Harvin spent the night in a hospital and was back on the sidelines watching practice Friday.

Here's a look at 10 important preseason injuries worth monitoring.

No. 10: Antonio Bryant, Bengals

Bryant still hasn't recovered from a nagging knee problem, which has sparked rumors that the Bengals could be looking to reach an injury settlement with the free agent who has yet to start running.

Bryant has officially been ruled out of the Bengals third preseason game and there is no timetable for his return.  Along with the famous Ochocinco-Owens duo, the Bengals have a great deal of depth at receiver.

A mutual parting might be best for both parties, but Byrant isn't likely to go walk unless he gets a decent chunk of his $28 million dollar contract.

No. 9: Eli Manning, Giants

Unlike many players on this list, Manning's prognosis is very positive.

Despite suffering a frightening head wound Monday night, Manning is expected to recover complete and is showing no ill-effects of the injury.  According to the New York Daily News, he will not play in the Giants' preseason game this weekend but is expected return to action in the preseason.

No. 8: Albert Haynesworth, Redskins

Haynesworth's ongoing saga with the Redskins has been a very amusing spectacle for NFL observers, but the Redskins aren't laughing.

Haynesworth missed practice Thursday but isn't expected to miss any time.  Don't be surprised if his nagging knee injury flares up again.

No matter what happens, the situation is certainly worth watching.  It will be interesting to see what impact the new nose tackle will have this season.

No. 7: Atari Bigby, Packers

Bigby spent the offseason complaining about his contract and promptly hurt his ankle while going through a simple conditioning drill early in camp.

The big-hitting safety has had a history of ankle problems and underwent surgery to hopefully repair the damage, but the broad timetable for his return suggests that he might not contribute much this season.

By the time he returns in 4-8 weeks, Bigby might be relegated to a minimal role on the defense.

No. 6: Jarius Byrd, Bills

Byrd, who impressed during his rookie season, isn't expected to return anytime soon after undergoing surgery to repair a groin injury that also ended his 2009 season.

The Bills have been vague about Bryd's injury in recent months, and until Thursday Chan Gailey refused to rule him out for the season opener.

It appears that Byrd will miss the majority of the season, meaning George Wilson will likely be the starting safety for the forseeable future.

No. 5: Kyle Kosier, Cowboys

Kosier is expected to miss around 4-6 weeks after suffering a torn MCL that will require surgery.  That's not good news for the Cowboys, who have concerns along the offensive line.

Dallas is already missing tackle Marc Colombo, who could return by the start of the regular season after undergoing athroscopic knee surgery.

No. 4: Sidney Rice, Vikings

Rice is not recovering rapidly from offseason hip surgery, which has the Vikings scrambling for answers to provide Brett Favre will reliable downfield targets.

Friday, the team worked out Favre's former teammate Javon Walker in hopes of adding depth to a thin receiving corps.

The Vikings still believe Rice could return for the first game of the regular season, but a return in Week Two or Week Three seems far more likely.

Rice himself said that a Week One return is "up in the air", according to the Minneapolis Star Tribune.

No. 3: Ed Reed, Ravens

Staying in the hip area, Ed Reed's prognosis for the upcoming season is still unclear.

Reed has reportedly seen specialists in Colorado and Georgia in recent weeks in an effort to accelerate his return.  His toughness gives the Ravens hope that he will be ready for Week One, but that seems a bit unlikely.

Reed remains on the PUP list, but is said to be progressing in his rehab.

No. 2: Percy Harvin, Vikings

Harvin's value to the Vikings in both the return game and as a receiver is obvious, but his future as an NFL player is extremely unclear.

Harvin has been released from the hospital and could be cleared to return by the start of the season.  Even if he is allowed to play, his history of severe migraines means the Vikings would be wise to start shopping for return men and veteran receivers--besides Javon Walker.

No. 1: Larry Fitzgerald, Cardinals

The Cardinals aren't officially in rebuilding mode yet, but any further damage to Larry Fitzgerald might chance that.

Fitzgerald suffered a sprained MCL in the Cardinals' preseason battle with the Texans Saturday, an injury that won't require surgery but will cause him to sit out the remainder of the preseason games.

If Fitzgerald recovers and stays healthy, the Cardinals will be competitive in the NFC West.  There is no question Arizona can ill-afford to lose the face of the franchise.
