Key injuries could determine playoff races in 2nd half

Just as important as filling a roster with skilled players is keeping that talent healthy.

In no place is that more apparent than the AFC North, which pretty much already has been decided by who has avoided sick bay.

The Bengals are 8-0 on merit, but other than linebacker Vontaze Burfict, they've stayed away from impactful injuries. The rest of the division has been an M.A.S.H. unit.

Baltimore is languishing at 2-6 in part because of an epidemic that has cost the Ravens their top defensive player, linebacker Terrell Suggs, and their one elite receiver, Steve Smith. Baltimore has 12 players on injured reserve and, shockingly considering its history for nearly two decades, is in the running for the top overall draft pick.

"You move on, That's what you have to do," coach John Harbaugh says. "It never changes. We're never going to use excuses, we're never going to say that we don't have enough firepower or enough ammunition. We're never going to say that because we don't believe it. We always believe that we've got players in the pipeline that can get the job done."

Cleveland also has been ravaged. Quarterback Josh McCown's gutsy display on the field despite a shoulder problem was admirable, if somewhat counterproductive. Star cornerback Joe Haden is battling concussion issues, as is safety Donte Whitner. Coach Mike Pettine is fortunate if he can find 11 supposedly healthy players to start on defense.

Then there's Pittsburgh, which saw Le'Veon Bell, its 2014 All-Pro running back, go out with a torn-up knee in Week 8. Now, it's QB Ben Roethlisberger, who already missed four games with a knee issue and hurt his left foot on Sunday. He's gone for at least one game, and with the Steelers at 5-4, that's a huge deal for their playoff chances.

Pittsburgh has remained competitive because of an improved defense, the magnificence of receiver Antonio Brown, and the timely signing in the offseason of DeAngelo Williams as a backup to Bell. But such major injuries eventually catch up to teams, and the Steelers still have Seattle, Indianapolis, Cincinnati and Denver on the schedule.

Of course, injuries have not been limited to that division, and several presumed contenders have flopped in great part because of them.

Dallas (2-6) is Exhibit A, with Tony Romo's collarbone following Dez Bryant's broken foot. Bryant is back, Romo will be by the end of the month, but not linebacker Sean Lee, the defensive leader, who is dealing with concussion issues. Even before Bryant and Romo went down, top cornerback Orlando Scandrick was lost for the season with a torn ACL.

Another prime example is Buffalo, which is at .500 despite a slew of problems, mostly to the offense. QB Tyrod Taylor (knee), receivers Sammy Watkins (ankle/hamstring), Percy Harvin (knee and hip and now done for 2015) and Marquise Goodwin (ribs), and RBs LeSean McCoy (hamstring) and rookie Karlos Williams (concussion) have been sidelined at various times.

That puts an extra burden on the defense, which is missing tackle Kyle Williams (knee) and safety Aaron Williams.
