Making things more impossible to believe, Sturgis suffered the concussion when he was hit by an errant punt while warming up.
Shortly before the game, the Eagles officially ruled Sturgis out with a concussion.
Injury Update: K Caleb Sturgis suffered a concussion during warmups. He will not play in tonight's game.— Philadelphia Eagles (@Eagles) August 18, 2016
It was confusing because he was, you know, warming up. And it's hard to get hurt when you're warming up, especially when the injury wasn't pre-existing.
But there Sturgis was, minding his own business, when a punt came flying in and whacked him in the head.
I've heard everything. #Eagles K Caleb Sturgis is out w/ a concussion. He suffered it when a punt hit him in the head. In pregame.— Aditi Kinkhabwala (@AKinkhabwala) August 18, 2016
There's obviously nothing funny about a concussion for an NFL player (or for any human, really), but it's a remarkable way to get injured, especially for a kicker and especially in a preseason game.
Of course, this is a good lesson to always keep your helmet on during warmups.
Caleb Sturgis won't be playing tonight. He got hit in the head with a punt during warm-ups. Didn't have helmet on. Cody Parkey all kicks.— Jeff McLane (@Jeff_McLane) August 18, 2016
As noted by McLane, this means Cody Parkey gets to kick, which is really bad news for Sturgis. The two are in a competition for the kicker position and a big night for Parkey (plus Sturgis being injured) really opens the door.
