In their third fight (each of which Edgar has won), Edgar tagged Penn at will from the opening bell until the bout's violent finish late in the third round.
Edgar outstruck Penn 159-60, including 90-16 in the significant strikes department.
"The Answer" also outgrappled Penn, a fellow Brazilian jiu-jitsu black belt. Edgar landed each of his three takedown attempts and passed Penn's notoriously tricky guard three times.

Edgar ran his record to 8-1 in non-title fights in the UFC with the win. The former lightweight champ has won back-to-back bouts since losing three straight title fights between February 2012 and February 2013.
Penn, conversely, lost for the third consecutive time and for the fifth time in his last seven outings. The former lightweight champ has won just once since losing his first bout with Edgar at UFC 112.
