Hamlin has opted to wait until the end of the season to have the knee repaired, a strategy which will surely be second-guessed if Hamlin doesn't make a strong run at the championship. Hamlin hasn't disclosed the severity of the injury, but it's obviously not bad enough yet to warrant immediate treatment.
The reason why this injury could be significant is that Hamlin's this year's trendy pick to unseat Johnson, which means that -- if history holds -- he won't get anywhere near Victory Lane for awhile. And if he does, he's probably not going to be doing any Edwards-style backflips off his car.
