Manny Pacquiao will face Timothy Bradley for the third time on April 9 at MGM Grand in Las Vegas, which is also expected to be the farewell fight of the Filipino boxing superstar.

But if Pacquiao decides to delay his retirement, Top Rank Promotions CEO Bob Arum already has a possible opponent in mind for the former pound-for-pound king -- unbeaten super lightweight champion Terence Crawford.

Arum told BoxingScene that he is not convinced that Pacquiao will retire after his upcoming bout against Bradley. Arum wants to stage the bout between Pacquiao and Crawford but conceded that it is still up to Pacquiao to decide on his future.

Crawford, who holds a 27-0 record with 19 knockout victories, is the reigning World Boxing Organization super lightweight champion. The 28-year-old was linked to a possible fight with Pacquiao late last year before the former eight-division world champion opted to face Bradley again.

After failing to get a shot at Pacquiao, Crawford and his camp accepted a title defense against Henry Lundy on Feb. 27 at Madison Square Garden. If he wins, Arum wants Crawford to have one more bout before the possible fight against Pacquiao later this year.

"If he beats Lundy, we'll do one more with Crawford in June or July and then I want to a big fight for Crawford, a big pay-per-view fight," Arum added. "We'll look at what's available. If Manny beat Bradley and decides that he wants to keep fighting, then Crawford is the perfect opponent."

Pacquiao, who has not fought since absorbing a unanimous decision loss to Floyd Mayweather in May last year, has remained firm on his previous stance that he will call it quits after his next fight.

The Filipino boxing superstar, who has 57 wins against six defeats and two draws, wants to focus on his political career, as he is running for a Senate seat in the Philippines this year.

While Pacquiao sounded 100 percent sure about retiring in April, Hall of Fame trainer Freddie Roach recently said that he does not think his prized fighter will not walk away from boxing this year.

"I don't think this is his last fight for some reason," Roach told RingTV. "I just don't see it because he has a lot left in him. His work ethic is still great. I'd be disappointed if this was his last fight. I've been with him a long time, we had a great run. I'll support whatever he does."
