It won't take either Pat Barry or Lavar Johnson long to get right back in the cage after knockout wins within the last two weeks.

The two heavyweight sluggers have agreed to face each other at the upcoming UFC on FOX 3 event this spring, the UFC confirmed early Tuesday morning.

Johnson (16-5) made his UFC debut at last weekend's UFC on FOX 2, knocking out Joey Beltran with a hail of first-round uppercuts. Meanwhile, Barry (7-4) returned to the win column at the UFC on FX show on Jan. 20, overcoming some early first-round troubles on the ground to KO Christian Morecraft.

Both fighters took nightly awards for their performances, with Johnson winning KO of the Night for becoming the first man ever to knockout Beltran, while Barry won a Fight of the Night award for his comeback.

Meanwhile, the UFC also confirmed that the previously announced lightweight bout pitting Nate Diaz vs. Jim Miller during the same show would serve as the evening's main event and be scheduled for five rounds. It is possible that the winner will become the No. 1 contender for the lightweight title, though the promotion did not confirm that.

UFC on FOX 3 will take place on May 5 at the Izod Center in East Rutherford, New Jersey.
