Guerrero stepped away from the ring in February while his wife battled leukemia.
Now, The Ghost from Gilroy returns against Roberto Arreita in Las Vegas on April 30. Guerrero says he is ready and excited.
"I'm excited to get back in the ring, doing what I love to do. My first love's getting better and now my second love comes, so you know, I can't wait. I'm excited about this fight. I've haven't fought going on eight months so it's time. I can't wait," said Guerrero.
