Mauricio "Shogun" Rua (16-3 MMA, 0-1 UFC) has re-injured his knee and has been scratched from a UFC 85 main event with Chuck Liddell (21-5 MMA, 16-4 UFC).

The news comes from Thomas Gerbasi of UFC.com.

According to the report, Rua ruptured the ACL in his left knee, which is the same injury that forced a surgery after a UFC 76 loss to Forrest Griffin.

UFC 75 takes place June 7 at the O2 Arena in London. The UFC will announce a replacement for Rua "shortly."

The 26-year-old made his octagon debut at UFC 76 and suffered an upset submission loss (via rear-naked choke) to Griffin. Prior to the bout, the Brazilian PRIDE veteran had won 12 of 13 fights. He recently underwent knee surgery but had returned to training earlier this year.

Rua will again go under the knife. There's no timetable for his return to the UFC
