Another UFC semi-main event bites the dust

Just a few days after the Rory MacDonald vs. B.J. Penn was canceled, at least for now, another major welterweight division match is off.

Josh Koscheck was diagnosed with a bulging disc in his lower back (a killer injury for a wrestler) and he's off the 9/1 UFC 151 show in Las Vegas, NV.

Koscheck vs. Jake Ellenberger was the No. 2 fight on the show behind Light Heavyweight Champion Jon Jones vs. Dan Henderson on top.
