MMAFighting.com's Ariel Helwani reported the booking on Tuesday night's edition of UFC Tonight.
UFC 162, the promotion's annual Fourth of July weekend pay-per-view, takes place July 6, 2013 at the MGM Grand Garden Arena in Las Vegas, NV. Leben vs. Craig is already the fourth middleweight bout booked for the event, joining Roger Gracie vs. Tim Kennedy, Mark Munoz vs. Tim Boetsch, and the night's headliner, UFC middleweight champion Anderson Silva vs. Chris Weidman.
After approaching contender status with a hot 2010 campaign, Leben (22-9) has fallen on hard times of late. The 32-year-old dropped two of his three contests in 2011, both via TKO, before testing positive for oxycodone and oxymorphone -- his second failed drug test -- which resulted in a one-year suspension.
Craig (8-1), meanwhile, looks to get back into the win column after suffering his first professional loss, a unanimous decision to Ronny Markes at UFC on FX 7. The 27-year-old opened his UFC career with consecutive victories, upsetting Kyle Noke before knocking out Rafael Natal with a highlight reel head kick.
