A gruesome toe injury to Anthony Perosh has forced the UFC to make a change to the UFC on FX 6 lineup for December.

Perosh will be forced out, with Igor Pokrajac stepping in to face Joey Beltran in Australia.

Perosh got his big toe caught between the mats and nearly ripped off during a recent training session. He is expected to resume workouts in about a month.

Pokrajac (25-9) has won three of his last four fights, but was submitted by Vinny Magalhaes earlier this year.

Beltran (14-8) made a return to the UFC at light heavyweight after going 1-4 in the heavyweight division. He topped James Te Huna in his most recent bout.

Here’s the Twitter post showing Perosh’s toe injury. Be forewarned, it is graphic in nature:
