Chad Mendes vs. Ricardo Lamas staredown pic from UFC Fight Night 63 weigh ins

The official weigh in event for UFC Fight Night 63: "Mendes vs. Lamas" went down earlier today (Fri., April 3, 2015) from inside the Patriot Center in Fairfax, Virginia (full results here), which means all 22 fighters are official for tomorrow's big shebang on FOX Sports 1.

That includes headliners Chad Mendes and Ricardo Lamas, who face off in the five-round featherweight main event from "Old Dominion." Mixed martial arts (MMA) fans got a sneak peek of their 145-pound showdown when "Money" came nose-to-nose with "The Bully" after stepping on the scale (see above).

In the lightweight co-main event, longtime combat sports veteran Jorge "Gamebred" Masvidal will try to stop the meteoric rise of power-punching TUF grad "Raging" Al Iaquinta, with the winner likely taking over an open slot in the top 10 of their division.

See them face off below.
