ALL ACCESS: Terence Crawford vs Errol Spence Jr | Epilogue | SHOWTIME

Terence Crawford proved Saturday night what he has assured an army of doubters for five-plus years, that he is indisputably the best welterweight in boxing.

Crawford dominated Errol Spence Jr., dropped him three times and knocked out the previously undefeated former champion in the ninth round of a Showtime Pay-Per-View main event at T-Mobile Arena. Referee Harvey Dock stopped their scheduled 12-round, 147-pound title unification fight at 2:32 of the ninth round, as Crawford hammered a bloodied, battered Spence with an array of power punches that knocked Spence all around the ring.

Spence was on his feet when the fight was stopped, but Crawford dropped him in the second round and twice during the seventh round. No prior opponent had dropped Spence in any of his first 28 professional fights.
