Brock Lesnar found out the hard way yesterday that you do not mess with a ring post. If you ram your head for real to the post, the post always wins.

And that’s what happened last night on RAW as Triple H ran Lesnar through the post. The former UFC champ either forgot to put his hands up or his brakes didn’t function as the back of his head went crashing through the steel structure, immediately opening him up.

Blood was flowing down Lesnar’s face but he didn’t seem to mind and continued to brawl with Triple H while sporting a crimson mask. He needed 18 staples to close the gash on his head after the segment was done. WWE.COM has photos of Lesnar getting fixed by the WWE medical team backstage at http://t.co/kD6J2Jmc6B
