Kell Brook vs. Errol Spence: LIVE Round By Round Scorecard, TV Channel, Actual Start Time For Boxing Event

Recap: Overcoming a hostile crowd and some tight early rounds that could have gone either way, Errol Spence (22-0, 19 KOs) won the IBF welterweight title in an 11th-round technical knockout over Kell Brook (36-2, 25 KOs) on Saturday night at Bramall Lane in Sheffield, England.

Spence showed poise in front of over 30,000 spectators that were almost entirely supporting Brook, a Sheffield native. The fight was extremely close for most of the rounds and many rounds could have gone either way.

The 10th round essentially decided the fight. An inspired Spence went on a barrage, pummeling Brook with shots to the face and body that forced Brook to take a knee. The Brit's left eye was swelling from the southpaw's punches, a serious situation considering Gennady Golovkin did damage to Brook's right eye when they fought in September. Spence absorbed some solid punches as Brook battled back, but it was not enough to keep the fight competitive.

In the 11th round, Spence simply kept the pressure on and Brook couldn't continue due to his eye. At 1:47, referee Howard Foster called the fight with Brook's eye looking bruised.

Spence was effective with his jab for most of the fight and attacked in the later rounds with some impressive combinations. However, Brook kept the fight very close for much of the first nine rounds by landing solid uppercuts and hard overhand rights.

All three judges scored the right for Spence, but the scorecards were almost even. Judge Adalaide Byrd scored the fight 97-92, Judge Alejandro Lopez scored the fight 96-93, and Judge Dave Parris scored it 95-94. International Business Times scored the fight, 97-92.

Spence barely celebrated after the fight ended. The 27-year-old referenced a long layoff for perhaps some problems dealing with Brook and gave himself a B- grade for his effort.

"He's a tricky fighter. He's awkward. He's very strong and he can punch," said Spence of Brook. "But I proved today that I have a chin and I have true grit."

It was easily the biggest win of Spence's career. The Texan said he hoped to fight either Manny Pacquiao or Keith Thurman next.
