UFC 161: Tyron Woodley vs. Jake Shields and Pat Barry vs. Shawn Jordan booked for Winnipeg

Who opened the Canadian floodgates?

Not long after UFC 161 got its main event between Renan Barao vs. Eddie Wineland (details here), promotion officials went ahead and added two more marquee match-ups to its upcoming pay-per-view (PPV) fight card, scheduled for June 15, 2013, at the MTS Centre in Winnipeg, Manitoba, Canada.

Veteran MMA reporter Neil Davidson brought word of the pending contests earlier today.

First up is a welterweight war pitting wrestling vs. jiu-jitsu as Tyron Woodley and Jake Shields hook 'em up in a battle of ex-Strikeforce headliners. "The Chosen One" was chosen to be part of the UFC roster earlier this year and Woodley (11-1) made the most of it, pasting Jay Hieron in the first round at UFC 156 in Las Vegas.

Now it's time to see if his sub defense is up to par.

Shields (27-6-1) has struggled to replicate his Strikeforce success inside the Octagon, going 2-2 with one no contest, which resulted from a failed drug test following his win over Ed Herman at UFC 150 last August. With the way UFC has been handing out pink slips, this could be a do-or-die situation.

That might not be an issue for Pat Barry (8-5), who takes on fellow heavyweight Shawn Jordan. "HD" is 5-5 with ZUFFA and has yet to win consecutive contests, but he's a fan favorite for his go-for-broke attack, which explains why he's only been to a decision once in 13 professional fights.

Only two less than "The Savage."

Jordan (14-4) cut his teeth in Bellator and Strikeforce before getting called up to the big show, where he is currently 2-1, thanks to wins over Oli Thompson and Mike Russow, sandwiched around a unanimous decision loss to longtime veteran Cheick Kongo.

Expect fireworks.

In addition to "Barao vs. Wineland," UFC 161 will also feature two pivotal light heavyweight bouts -- Antonio Rogerio Nogueira vs. Mauricio Rua and Dan Henderson vs. Rashad Evans -- who are currently slated to take place on the PPV main card.
