The middleweight title fight between champion Gennady Golovkin and Marco Antonio Rubio set for Saturday at StubHub Center (on HBO) has proven to be quite the hot ticket. K2 Promotions, which promotes Golovkin, already put an extra 300 seats on sale and they sold out. Now, 284 more bleacher seats will go on sale Tuesday at noon.

Those tickets are priced at $53, which does not include service fees. They can be purchased by calling 888-929-7849, as well as by visiting the StubHub Center box office Monday through Friday until 6 p.m.
