UFC 143: Matt Riddle in for Amir Sadollah, Ricardo Lamas Out

A couple of changes were announced by Zuffa today for the UFC 143 card that is scheduled for February 4th in Vegas. One sees a TUF contestant replacing a TUF winner, and the other has Dustin Poirier looking for yet another opponent. Via UFC.com:

TUF 7 winner Amir Sadollah has been injured. Stepping in to face Wanderlei-Silva trained striker Jorge Lopez will be welterweight Matthew Riddle. - verbal agreements are in for this matchup. Riddle was slated to scrap at this past weekend's UFC 141, but forced to withdraw at the zero hour due to illness.

Also on that card, featherweight Dustin Poirier has lost his second opponent, as Ricardo Lamas has been injured. Lamas was only recently announced as the replacement for Poirier's original opponent, Erik Koch, who was also hurt. A replacement is expected to be named shortly.

Riddle's mysterious sickness that led to the cancellation of his bout with Luis Ramos last weekend hasn't been explained yet, but apparently it's nothing serious and he's ready to go again. He is currently on a two-fight losing streak. Lopez lost his UFC debut to Justin Edwards back at UFC Fight Night 25 in September, so this is an extremely important bout for the futures of both men.
