It appears that the fight card for UFC Fight Night 20 has been filled out as welterweights Amir Sadollah and veteran Brad Blackburn will more than likely take the final main card slot for the event, scheduled to take place on January 11, 2010 from the Patriot Center in Fairfax, VA.

The bout has been agreed upon by both parties but no agreements have been signed as of this posting.

After defeating C.B. Dollaway and becoming the surprise winner at TUF 8 back in June 2008, Sadollah battled injuries and illness, which forced him out of the Octagon for approximately 14 months. He would return in August and suffer a TKO loss to Johny Hendricks at UFC 101 but would rebound by outlasting Phil Baroni for an unanimous decision win at UFC 106.

Meanwhile, Blackburn is looking to improve his current 5-0 record in the UFC, with victories over James Giboo, Ryo Chonan and Edgar Garcia. With the inevitable Sadollah-Blackburn signing, the UFC Fight Night 20 fight card looks like this:
