Inglewood, California — Juan Manuel Marquez will return to the ring to face Mike Alvarado on May 17 at the newly renovated Forum. Top Rank announced the 12-round bout Thursday. The promotional company also says the winner will face the winner of Manny Pacquiao’s April 12 rematch with Timothy Bradley for the WBO welterweight title. The 40-year-old Marquez (55-7-1) hasn’t fought since losing a split decision to Bradley last October. The four-division world champion fought 12 times at the Forum early in his career. Alvarado (34-2) was stopped by Ruslan Provodnikov in his last bout, losing the WBO 140-pound title. The Forum is getting back in the boxing business after its purchase and renovation by the company that owns Madison Square Garden.
