UFC 146: "Dos Santos vs. Overeem" features an all heavyweight main card that will culminate in a 265-pound championship showdown pitting Junior dos Santos defending his strap against former Strikeforce king Alistair Overeem.

Before the pay-per-view kicks off, though, a stacked preliminary card features quite a few household names, one of which is Jason Miller. You may remember him from his stint coaching The Ultimate Fighter (TUF) 14 opposite Michael Bisping. You may have quickly forgotten him, too, thanks to the head-scratching performance he turned in against "The Count" at the live Finale back on Dec. 3, 2011, in Las Vegas, Nevada.

He was so bad that night, UFC President Dana White basically threatened his job and publicly pondered his future fighting inside the Octagon. "Mayhem" went on the offensive and started a Twitter campaign to get himself one more chance with the promotion and damned if it didn't work.

Now he's got a date with C.B. Dollaway this coming Memorial Day weekend (May 26, 2012) at the MGM Grand Garden Arena in "Sin City." Win and he's back in the boss's good graces, lose and he's likely looking for work elsewhere.

Miller is taking this task quite serious, as you can see in the photo above, and thanks to Scott Hirano of LowKick.com we can check out a complete gallery of how hard he's going in training in preparation for the fight of his career. Check it all out after the jump.
