Freddie Roach said the loser of the Nov. 23 welterweight clash between Manny Pacquiao and rising junior welterweight contender Brandon Rios may be “finished” during an with RingTV.com in May.

But the Hall of Fame trainer was even more emphatic in regard to Pacquiao, the fighter he trains, according to a recent report by Yahoo!Sports.

“It’s over, 100 percent” if Pacquiao is knocked out by Rios, said Roach. “We have a deal. When I tell him it’s over, he’ll say it’s over and that’s it. He’s pretty loyal with his words, and if that happens, it will be the end.”

Pacquiao (54-5-2, 38 knockouts), who turns 35 in December, will face Rios (31-1, 23 KOs) in Macau on HBO Pay Per View in an attempt to rebound from consecutive losses by disputed split-decision to WBO beltholder Tim Bradley and sixth-round knockout to Juan Manuel Marquez last year.

Rios, who tuned 27 in April is coming off a unanimous decision loss to Mike Alvarado in March that was a rematch of Rios’ seventh-round stoppage win over Alvarado last October.

Rios, meanwhile, has said that it was his goal “to go out to and to dominate” Pacquiao, adding, “when I catch his ass, he’s going to go down.”

Roach calls Pacquiao’s fight with Rios a shot at “sweet revenge” for a November of 2010 video in which Rios and now-retired former welterweight titleholder Antonio Margarito appeared to mock Roach’s Parkinson’s disease.
