Watch: Must-see finishes from Saturday's ACB 67

Russian outfit Absolute Championship Berkut has made incessant action the mandate over its three-year existence, and Saturday's card was no exception.

From the awe-inspiring to the devastating to the downright bizarre, here are the most memorable stoppages from ACB 67 in Grozny, Chechnya.

Welterweight Championship Bout: Mukhamed Berkhamov def. Brett Cooper via 2nd-round KO

Berkhamov made sure the main event lived up to its billing.

The 23-year-old showed no respect for Cooper's knockout-riddled resume, nor his edge in experience, as he left the veteran limp with a nasty counter left hook in the second round to bring the welterweight gold back to Russia.

Berkhamov improved to a perfect 12-0 with just the second KO of his career.

Lightweight Bout: Alexandr Shabily def. Gleristone Santos via 1st-round KO

Timing is everything, even when your back is against the fence.

Unfazed by Santos' stalking ways, Shabily stoically countered his foe's reckless flurry with an expertly timed knee to the kisser before leaving him lifeless with some nasty follow-up punches.

Bantamweight Bout: Magomed Magomedov def. Dean Garnett via 1st-round submission (guillotine choke)

They may have shared the cage for only four minutes, but Magomedov and Garnett came with something for everyone.

Garnett struck first with a stiff right hand to the forehead, Magomedov with a straight right timed perfectly off his foe's low kick. The Englishman couldn't match Magomedov in the grappling department, however, as the Russian fended off a kimura attempt to end the ensuing scramble with a mounted guillotine for the tapout.

Lightweight Bout: Rasul Shovhalov def. Tiago Trator via 1st-round TKO

Shovhalov dished out a beating, then revealed his inner-bleeding heart.

The Russian lightweight first put Trator on the canvas with an onslaught of haymakers, then unleashed some garden variety ground-and-pound until he decided enough punishment had been exacted and abruptly raised his hand in victory, leaving referee Herb Dean no choice but to take his cue to wave it all off just 2:17 in.

Who needs a third man in the cage?

Light Heavyweight Bout: Jose Daniel Toledo Canellas def. Muslim Makhmudov via 1st-round KO

Leave it to the big boys to reenact a game of rock'em sock'em robots.

As men of their size and power are want to do, Canellas and Makhmudov traded bombs of all kinds for three minutes and change, with the Spaniard getting the last laugh thanks to a blistering right hand that wilted Makhmudov to the canvas.

Lightweight Bout: Amirkhan Adaev def. Otavio dos Santos via 2nd-round TKO

Dos Santos looked to the referee for a stoppage after raining fists and elbows on Adaev from full mount in Round 1, and the Russian made him pay for it.

Adaev took advantage of DEos Santos' brief respite to escape the precarious position and make it to the second-round bell, after which he put the Brazilian on his hind parts with a right hand, then returned the hellfire he'd eaten in the first round tenfold for the TKO at the 1:17 mark.
