Rich Hofmann | It's time for No. 5 to look out for No. 1 on the health frontTHE QUARTERBACK was injured Sunday - that much was obvious enough. An injury in a previously injured area had been aggravated. There was pain, and there were some limitations on his functionality, and everybody involved knew it. But the game was close and the need was great and the quarterback read the situation and did what he believed was called for in that situation. He played.When it was over, the quarterback said, "I've been through a lot worse. It just seems like it's common routine for me: Find a way to play through an injury and deal with it and go from there."The quarterback?The New York Jets' Chad Pennington.It happens every week in the NFL, where neither health nor contracts are guaranteed, where the profits are always sustainable and the players are always disposable. It is not just Donovan McNabb. It is not just David Akers. It is everywhere and it is every week.Because of that, it is hard to know what to say right now about McNabb, and how he should handle the immediatefuture. Eagles coach Andy Reid says McNabb's bruised sternum continues to bother him, and his strained abdomen continues to bother him, and he now has a bruised shin, too. There isn't enough room on his uniform to attach all the bull's-eyes.Part of you wants to scream that McNabb should sit out for a few weeks here, and if there was a doctor willing to say that he would be completely healthy if he took off a few games, it would be a scream that even McNabb - historically deaf to all such entreaties - just might hear.This would be the logic: You miss the next two games, at Kansas City and Dallas, and hope your teammates can keep from collapsing in your absence. Those 2 weeks, followed by the Eagles' bye week, might just be enough - and then, the theory would go, McNabb would be healthy for the important part of the season. This team loses very few games after Nov. 1 under Andy Reid, and a healthy quarterback would be the Eagles' best chance to continue that pattern. There is a problem, though. Nobody knows if rest is the answer here.Abdominal injuries are underrated cripplers in pro sports. That modern athletic training is so focused now on strengthening an athlete's core - the muscles in his trunk - tells you just how important this area is.At the risk of showing too much age, it is not hard to remember in the 1980s when the great Roynell Young went from being an All-Pro player for the Eagles to just another cornerback after suffering some kind of abdominal strain or tear that robbed him of a season, and more. It was a baffling thing to many people at the time - it's just a pulled muscle, right? - but the implications for that player were enormous, and he wasn't the only one, and he isn't the only one.Now, McNabb either has a strained abdomen or he has a sports hernia; the Eagles are calling it the former, the concern is that it is the latter, and McNabb said Sunday he might be interested in getting another medical opinion. Reid said yesterday it might happen or it might not.One thing is clear: McNabb had better take charge here.Because if he says he can play, Reid will let him play - just as he allowed McNabb to continue Sunday despite some obvious problems, just as he allowed Akers to kick Sunday despite some common-sense concerns.Reid is no different than the rest of the people in his profession - no different than the Jets' Herm Edwards (who, just to close the circle, played cornerback opposite Roynell Young for years in the Eagles' secondary). The player wants to play if he can and the coach wants him to play if he can - and that goes double for quarterbacks, whoall quickly learn three things at their fraternity initiation: that the money is great, that abaseball cap on the sideline isrequired, and that you never leave a game voluntarily."You first look at the medical evidence and try to exhaust that," Reid said. "We go to the nth degree to try to do that and then you work from there. You talk to the doctors and talk to the player and have to take a bunch of information in, try to come up with the right answer."The problem is that the evidence isn't always clear-cut.At that point, the player rules - and the player isn't coming out, because that is the player's reflex. For a marginal guy, worried about his future, that is a risky bit of business. For a star - someone of McNabb's stature, or to bring up a rotten memory, of Eric Lindros' stature back in his Flyers days - it is different. Someone like that has the power to make a rational decision that will carry no repercussions.McNabb clearly has that power, even if he has never exercised it. As for the here and now, the right decision is not obvious.You hope for his sake that somebody can answer the two key questions: Would rest make adifference, and is there a risk of something really serious happening if he continues playing?For Donovan McNabb's sake, the hope here is for some answers, some clarity. Without them, all he has is the quarterback's reflex, and we all know what that is.As Chad Pennington said Sunday, the day before it was reported his rotator cuff was torn and his season was over, "They'll have to cut it off for me not to play."
