Boxer James Kirkland -- He Wasn't Ready for Canelo ... Says Ex-Trainer Ann Wolfe

James Kirkland was simply not prepared to step in the ring with a fighter like Canelo Alvarez ... so says his legendary ex-trainer Ann Wolfe who tells TMZ Sports he took the fight way too soon. Kirkland was KNOCKED OUT in the 3rd round of his fight with Alvarez this weekend ... after parting ways with Wolfe (his longtime trainer) earlier this year. Wolfe says she has NO BAD BLOOD toward Kirkland ... and although they didn't speak after the fight, she called James' mother afterward to make sure he was OK.
