Glover Teixeira knows that he will receive quite possibly the biggest challenge of his career when he meets former UFC light heavyweight champion Quinton “Rampage” Jackson.

Teixeira and Jackson will take place in October at UFC 153 from Brazil.

For Teixeira, he is hoping that the best Jackson ever shows up in Rio de Janeiro.

“I’m waiting for an 100-percent prepared ‘Rampage,'” said Teixeira, in a recent interview with Tatame. “I’m training to fight old times Pride ‘Rampage.’ I’m preparing for the fighter he was when he got into the UFC.”

Jackson has fallen on hard times as of late. After being submitted by Jon Jones in a bout for the UFC light heavyweight title, Jackson was topped by Ryan Bader.

Teixeira, meanwhile, earned his first UFC victory by stopping Kyle Kingsbury earlier this year. He is 18-2 in his career, including 11 knockout victories.
