Welcome to SportsNation! On Thursday, boxing trainer Freddie Roach will stop by to chat about Saturday's Manny Pacquiao-Timothy Bradley fight.

Roach currently trains Pacquiao (54-3-2, 38 KO), who is set to make the fourth defense of his WBO welterweight title in the last three years against the undefeated Bradley (28-0, 12 KO). Pacquiao has won titles in a boxing-record eight different weight classes. The MGM Grand in Las Vegas will host the bout Saturday at 9 p.m. ET/6 p.m. PT on HBO PPV.

Roach, a Massachusetts native, won the trainer of the year award in 2003, 2006, 2008 and 2009. As a professional boxer, Roach went 39-15 before retiring in 1986.
