The injured hand suffered by Welterweight champion boxer Floyd Mayweather Jr. in Saturday night's win over Robert Guerrero will be okay.

"He went to hospital [Saturday] night, and everything is fine," Mayweather's publicist told ESPN. "He just experienced some soreness."

Mayweather said he couldn't knock Guerrero out because he hurt his right hand late in the fight, according to the Associated Press. After the match, he showed reporters his hand: it looked swollen and discolored. 

"I was looking for the knockout but I hurt my hand," Mayweather said. "I feel bad I didn't give the fans the knockout."

Despite injuring his hand, Mayweather went on to win the match by a unanimous 12-round decision.  All three judges scored the fight 117-111. 

Mayweather showed no signs of rust in his first match back in over a year. He landed 195 punches compared to Guerrero's 113. 

Mayweather delivered a bevy of right hands and counters throughout the fight. The 36-year-old was spry on his feet and his defense looked to frustrate Guerrero, who had trouble landing punches. 

"After the Cotto fight I realized my defense wasn't what it should be and I had to hone my skills," Mayweather said. "My defense was on point and (my father) told me to stick with my defense and that the less you get hit the longer you last."

The healthy diagnosis for Mayweather's hand is good news for boxing fans. As part of his six-fight deal with Showtime, Mayweather is expected to fight Sept. 14.  His opponent has yet to be determined.

Fans are eager though to see Mayweather square off against Canelo Alvarez.  Alvarez has a 41-0-1 record, along with 30 knockouts.  Mayweather, however, wouldn't confirm his next opponent.

"They're going to keep making opponents," Mayweather said about Alvarez. "This is not going to stop.  And I'm not saying Canelo is not a good fighter.  But I'm happy with my victory tonight and all I'm going to do is take one day at a time."
