Today UFC officials announced yet another change to their fight card at UFC 149 in Calgary. George Roop, who was scheduled to fight Antonio Carvalho, had to pull out due to a training injury. He will be replaced by Daniel Pineda, who has already come in on short notice twice for the UFC. Pineda is coming off of a hard fought decision loss to Mike Brown at UFC 146 which saw him nearly mount a comeback late in the third round. Prior to that loss, he was coming off of two impressive submission wins over Pat Schilling and Mackens Semerzier respectively, the latter of which could arguably could have won him submission of the night. Pineda clearly is doing his best to get on the UFC's good side, and it's very respectable. He made his debut this January and is already going to have had his fourth Octagon appearance come July. He has finished every single one of his wins, and attacks with submissions with reckless abandon.

Carvalho is a pretty talented fighter, but is coming off of a tough loss to Felipe Arantes at UFC 142. He has a 13-5 record and boasts a split decision win over Hatsu Hioki, a fighter who was offered a featherweight title shot from the UFC. This will be his second fight with the UFC, and it may very likely be a sink or swim situation for him.

The prospect of this fight is very interesting, and can be back and forth in both the standing and ground exchanges. Pineda has a reckless grappling style which has resulted in an impressive 11 submission wins, while Carvalho is noted for excellent grappling. Pineda's recklessness grappling translates into his striking style, whereas Carvalho focuses more on reserved techniques standing. I expect scrambles on the mat and fireworks on the feet.
