Here's the sad injury of the day. And by sad, I mean pathetic.

Ever see that show on Spike TV called Pros vs. Joes? A bunch of never-been amateurs compete in sporting events against a bunch of ex-jocks trying to relive their glory days. Actually kind of sad all around, if you think about it. I don't know whom to feel more bad for -- the Joe Schmoes who actually think they're even in the same hemisphere as being able to compete with professional athletes or the former jocks who have reduced themselves to dominating some construction worker from Buffalo.

Anyway, all former NBA player Derrick Coleman had to do was box out two Joes (one at a time) for 10 rebounds. The first round was no problem, as DC allowed only two rebounds to his opponent. But against a salesman from Philadelphia, Coleman landed awkwardly, injured his knee and had to sit out the rest of the show.

Somewhere in Philly, a long-suffering Sixers fan is either laughing or cursing. Or both.
