Anderson Silva returned from a horrific leg injury to earn a unanimous decision over Nick Diaz in the UFC 183 main event Saturday.

After completing his 18-month suspension, Nick Diaz said he's still the top welterweight in UFC and he's in no rush to accept a fight against titleholder Tyron Woodley.

He first arrived in the UFC in 2021 with plenty of talk surrounding him due to his status as Nate Diaz’s protégé and a fellow member of the Nick Diaz army.
