The stars are easy enough to keep track of, especially when they go down on national television with everyone watching.
That's what happened with tough guy Rob Gronkowski, last seen lying almost immobile on the ground and screaming in pain after taking a big hit that ended his already abbreviated season. The bruising — and often bruised — New England tight end is only 24, but the surgery for his torn ACL is his sixth in little more than a year and every one of them exacts some sort of toll.
And then there was Wes Welker, streaking fearlessly across the middle only to be leveled with a shot to the shoulders and head for his second concussion in four games. Why the Denver receiver would ever set foot on the field again is a mystery when we're learning more about the cumulative effects from getting hit in the head, but you can bet he will.
The season also is over in Washington for Robert Griffin III, though he's still mobile even after being sacked 24 times in his last five games. The Redskins are so worried their franchise quarterback will be hurt again that he was benched with three games remaining in the season rather than take the risk.
"If he did play, and something happened to him, I think it would set our franchise back," embattled Redskins coach Mike Shanahan said.
Unfortunately, not as much precautionary care is taken with players who aren't stars. Far too often they play through injuries because if they don't play they might soon find themselves out of a job. It's a fact of life in a league where contracts aren't guaranteed and there are no guarantees the next play could be your last.
It's no secret football is a brutal game. Tough men play it, and sometimes they pay the price. The big hits their bodies endure are part of the very fabric of the game, and a big reason why the NFL is far and away the most popular sports league in the country.
But of all the stats in Week 15 of a typically violent NFL season, there are a few that should give anyone who pays the game some pause. Injuries are once again piling up at a disturbing rate, even in a league where injury reports are often long.
A tally of the NFL injury list before Sunday's games showed a startling 254 players — an average of about eight per team — out for the season with injuries ranging from busted ribs to foggy heads. Another 131 players were either out for this week's games or listed as doubtful or questionable to play.
That's 385 players with significant injuries out of about 2,000 who will play in the NFL this season. And that's just a weekly snapshot in a league where making it through the season without injury is almost as rare as being fitted for a Super Bowl ring.
