Michael Johnson vs. Melvin Guillard booked for UFC Fight Night 37 with Ross Pearson hurt

Surging Ultimate Fighting Championship (UFC) lightweight contender Michael Johnson will take on fellow Ultimate Fighter (TUF) veteran Melvin Guillard on the upcoming UFC Fight Night 37 fight card, which is set to go down inside the O2 Arena in London, England, on March 8, 2014, via the promotion's new "Fight Pass" network.

UFC officials announced the switcheroo on Wednesday.

Guillard (31-12) was expected to throw hands opposite Ross Pearson in a rematch to settle their "No Contest" from last October; however, "The Real Deal" got real hurt and had to withdraw.
