An injury has forced welterweight Lance Benoist (6-2 MMA, 1-2 UFC) off next month’s UFC on FX 8 card, and Brazilian UFC newcomer Michel Richard dos Prazeres (16-0 MMA, 0-0 UFC) will step in to meet Paulo Thiago (14-5 MMA, 4-5 UFC).

The fight switch was first reported by Brazilian news outlet Globo.com, though UFC officials have yet to make a formal announcement of the change.

UFC on FX 8 takes place May 18 at Arena Jaragua in Jaragua do Sul, Santa Catarina, Brazil. The event’s main card airs live on FX following prelims on FUEL TV and Facebook.

Prazeres will make his UFC debut as an unbeaten welterweight with half of his wins by submission. But the Brazilian has competed just twice since 2010 and just four times since 2007. Prazeres first fought professionally in 2000 and won his first four fights by submission.

Thiago is 1-4 in his past five fights with just a decision win over David Mitchell at UFC 134 on the good side of the ledger for him. His losses in that stretch have come to Dong Hyun Kim, Siyar Bahadurzada, Diego Sanchez and Martin Kampmann.

Benoist was looking to get back in the win column after back-to-back losses to Seth Baczynski and Sean Pierson, which halted the perfect 6-0 start to his pro career.
