It was a bloody eventful morning in Pittsburgh.

Just moments before the team announced the acquisition of David Perron, two long-standing Penguins soaked their pads with more than just sweat in preparation for Friday's clash versus the Tampa Bay Lightning.

Evgeni Malkin reportedly caught Craig Adams in the mouth during a battle drill, which resulted in the pair exchanging blows, according to the Pittsburgh Tribune-Review's Josh Yohe.

Here's a photo taken of the aftermath by a local photographer:

Malkin, seen in the bottom right corner, appears to have lost his helmet and shoulder pads, but Adams is certainly the one who looks worse for wear.
