Raiders' Denver Kirkland: Suffering from muscle cramps

Kirkland was carted off the field Friday due to muscle cramps, Michael Gehlken of the Las Vegas Review-Journal reports.

The situation was scary to onlookers, as typically being carted off the field indicates a serious injury. Fortunately, Kirkland was just suffering from cramps. The 25-year-old is on the roster bubble, so a return sooner rather than later will be beneficial for his chances of serving as a depth lineman.
