For the first time since winning the Strikeforce Middleweight Championship in August of 2010, Jacaré Souza defended his title on Saturday night at the Strikeforce event at the HP Pavilion in San Jose, CA.

And at the end of the night, Souza walked out of the cage with his title as he submitted Robbie Lawler with a rear naked choke at 2:00 of the third round.

Herschel Walker is a beast. After hearing his comments earlier in the week that he could still play football, I can see why he was thinking about it. The man is absolutely jacked right now.

In the second fight of the Strikeforce event on Saturday night at the HP Pavilion in San Jose, CA, Walker beat Scott Carson by TKO (strikes) at 3:13 of the first round.

In the first match on the main card at the Strikeforce event on Saturday at the HP Pavilion in San Jose, CA, Roger Gracie submitted Trevor Prangley via a rear-naked choke at 4:19 of the first round.

In the last event ever for the WEC, Anthony Pettis delivered one amazing kick that I can't even explain against Ben Henderson. Pettis went on to win the WEC Lightweight Championship and will now face Frankie Edgar or Gray Maynard in the UFC.

Here's that amazing kick for enjoyment:

If there was any doubt that Georges St. Pierre is the best pound-for-pound fighter in the UFC and MMA, there was definitely none after he completely dismantled Josh Koscheck to retain his UFC Welterweight belt at UFC 124 at Bell Centre, Montreal, Quebec.

It's not too often, if it all, you see someone in MMA come out and use a jab.

Well that's exactly what GSP as it was his constant jabs to the right eye of Koscheck that really set the tone of this bout. Having to consistently protect his eye, Koscheck was never really able to mount any attack and GSP, being the best at what he does, took full advantage of that.

GSP was very technical with his punches and kicks throughout the fight, especially with that jab. He was never in a real danger even with Koscheck landing a few uppercuts.

It will be interesting to see who GSP will fight next in the 170 lb weight class. Could it be Thiago Alves who fought probably the best fight of his career in the first fight of the main card? GSP has already beaten him once.

Only UFC president Dana White knows that answer.

Here's the fight replay plus the post-fight interviews of GSP and Koscheck with Joe Rogan.

Standing at 6'11", Stefan Struve is the tallest fighter in the UFC. With long legs, he can use those to his advantage when he's on the ground.

And that's exactly what he did on Saturday night at the Bell Centre in Montreal, Quebec as he scored a TKO win (punches over Sean McCorkle at 3:55 of the first round.

With McCorkle on top of him, he was able to use his long legs to flip McCorkle on his back where he then proceeded in a little ground and pound until the fight was stopped.

The up-and-comer Charles Oliveira entered The Octagon on Saturday night at the Bell Centre in Montreal, Quebec as winner in both of his fights in the UFC. But at the end of the night, it was the veteran Jim Miller who walked victorious.

Miller ended up winning by submission (kneebar) at 1:59 of the first round to pick up his sixth straight win.

During the post-fight interview Joe Rogan, Miller demanded that he be given a chance to fight for the lightweight title.

During the second fight on the main card at UFC 124 at the Bell Centre in Montreal, Quebec, Mac Danzig delivered the knockout blow to the jaw of Joe Stevenson to pick up the win.

Danzig had lost four out his last five bouts but took advantage of Stevenson who left himself open on a combination that was met by a vicious left hook by Danzig sending "Daddy" to the floor.
