That UFC Boston undercard just can't seem to stay together. Augusto "Tanquinho" Mendes was brought in on short notice to replace featherweight Jim Hettes, after Hettes suffered a bad knee injury. Now, unfortunately, it looks like Mendes is out with an injury as well, and Charles Rosa, Hettes' original opponent will be getting his second re-booking in less than a week. Kyle Bochniak will step in for Mendes against Rosa on just a few days notice, as confirmed by Dave Sholler, the news of his signing was first made public via his gym's Facebook page.
