Tonight at 9 pm EST on Showtime, BoxNation (UK), and PPV (Puerto Rico and Australia), Miguel Cotto returns to Madison Square Garden to take on Austin Trout in the main event, for Trout's WBA "regular" junior middleweight title.

BoxNation subscribers can stream the fight at Livesport.TV, but there are no legal U.S. streams for the event.

Cotto (37-3, 30 KO) has never lost at the Garden, with a 7-0 career record at his adopted home arena so far. For Trout (25-0, 14 KO), it's his first fight at the building, and his first major main event of any kind, really.

On the undercard, Jayson Velez (19-0, 14 KO) of Puerto Rico meets Mexico's Salvador Sanchez II (30-4-3, 18 KO) in a 10-round featherweight bout with the WBC silver title on the line. Also televised will be comebacking middleweight Danny Jacobs (23-1, 20 KO). He'll take on Chris Fitzpatrick (15-2, 6 KO) in another bout scheduled for 10 rounds.

We'll be here with round-by-round updates and immediate post-fight analysis of each bout. Join us tonight at 9!
