The scouting report suggests that former two-division champion Ivan Calderon has a monumental task ahead of him this weekend.

The 37-year oid returns to his roots in hopes of reclaiming his old strawweight belt against current titlist Moises Fuentes (15-1, 7KO). The bout serves as the chief support for a pay-per-view show airing live from Coliseo Ruben Rodriguez in Bayamon, Puerto Rico. Wilfredo Vazquez Jr. faces Jonathan Oquendo in the evening's main event.

Calderon opted to return to the strawweight limit last year, shortly after suffering his second consecutive knockout loss to Giovani Segura at junior flyweight. A tuneup bout last October - a 10-round split decision over Felipe Rivas - marked his first fight without a title at stake in more than seven years.

The first loss to Segura - a 7th round knockout in Aug. '10 - ended a three-year stay as lineal junior flyweight king, which came on the heels of a four-year run as an unbeaten strawweight titlist. His past three fights have suggested that it's perhaps time to hang 'em up and hope than a call for Canastota and the Boxing Hall of Fame awaits in his future.

Calderon (35-2-1, 6KO) isn't quite ready to subscribe to that theory, nor has he chosen the easy route in hopes of re-entering the title fray. More than 10 years younger and a massive eight inches taller, Fuentes looks the part and is a considerble favorite to return home to Mexico with his alphabet title still in tow.

Of course, plenty of fighters in boxing history have avoided Father Time. Calderon turns to history rather than oddsmakers in preaching his belief of an upset in the making.

"Everybody talks about my age, but look at what (lineal middleweight champion Sergio) 'Maravilla' Martinez did to Julio Cesar Chavez Jr," Calderon cites as a recent example of experience over youth at the sport's top level. "I'm well-trained for this fight and ready to regain my old title."

Fuentes weighed 104.5 lb for the second defense of the title he won 14 months ago. The bout is his first outside of his native Mexico.

Calderon, who was slightly heavier at 104.8 lb - fights at home for the 22nd time in his career. He has won all but one, that being the first loss to Segura two years ago.
