No big injuries, beyond the standard "I'm going to feel that tomorrow" overexertion. I did drag the toe of my foot through the dirt while attempting a kickoff. You usually don't take divots on kickoffs, but this was an exception :-)
Today I'm a little sore and stiff in the legs and the back, but a couple days of working out and stretching should ease that pain. So I think we can call fleetball a rousing success! All had a good time, and were interested in playing again in the future.
