The weather has been unseasonably cool in St. Joseph, Missouri for Kansas City Chiefs training camp so you can't blame that when looking at all these hamstring injuries. The Chiefs gotta be near the lead league in hamstring injuries so far during camp.
Herbie Teope ran down a few injury notes and noted that there are five Chiefs currently who have a hamstring injury, including AJ Jenkins, Mark Harrison, Junior Hemingway, Charcandrick West and Jermelle Cudjo. Counting Kyle Williams, who returned from a hamstring injury on Saturday, that's four receivers with hamstring injuries in the last week alone. Marcus Cooper had a hammy earlier in camp. (Update: And Cooper just left practice again. Another hammy?)
Why so many hamstring injuries?
"It happens," Andy Reid said this week. "It happens as you go through camp, your legs get tired. You get those camp strings, those tight hamstrings. We'll be fine."
The most likely answer is that there is no good reason. Injuries happen by chance. It's usually not an environment thing. There is very little down time at Andy Reid's training camp. With the amount of passing they do, the receivers are required to do a lot of running. Reid's camps are also tough, physical camps. Combining all that, I suppose I can see how you can come up with a recipe for increased hamstring injuries.
It does seem like there has been more than usual this year. Luckily they're mostly just ticky-tack stuff. Sanders Commings appears to be the only significant injury at this point.
