Hardy (23-9) was able to shed the half pound within the one-hour period after the weigh-in. As a result, Hardy will not receive a penalty on his fight purse.
All other 23 fighters on Sunday's card came in on weight, including Lytle (30-18-5), who tipped the scales at 170.5 pounds. The card features eight preliminary bouts and four on the main card.
Former light heavyweight Jared Hamman successfully cut to the middleweight division for the first time in his career. Hamman (12-3) made the decision to cut 20 pounds after going 1-2 in his first three fights in the UFC, including a knockout loss to prospect Alexander Gustafsson in Nov. 2009.
Lightweight contenders Jim Miller (20-2) and Ben Henderson (13-2) will serve as the night's co-main event. Henderson immediately asked for a towel before stepping onto the scale, knowing he'd have to shed his entire wardrobe to make the 156-pound limit. Miller came in at 155.5.
