Shane Mosley was anything but sweet. He was a winner, though, with his sights set on bigger things.

Mosley won his second straight fight since moving back down to welterweight Saturday night, beating Jose Luiz Cruz on a unanimous decision.

The fight was held just after a bout at the MGM Grand hotel-casino in which IBF lightweight champion Leavander Johnson suffered a brain injury and underwent surgery at a local hospital to relieve pressure on his brain.

Mosley won his 10-round fight easily on all three scorecards but was unimpressive in beating Cruz. One judge had it 98-92, the second scored it 97-93 and the third 96-94.

Still, he said he was ready to take on the best in the 147-pound division.

``I wish I would have knocked him out but I'll take the win,'' Mosley said. ``I feel like I'm definitely at the top now. I'll fight anybody, (Antonio) Margarito (Zab) Judah.''

Mosley, who moved down from 154 pounds after losing two decisions to Winky Wright, showed little of the speed that marked his early career and landed only one punch at a time.

But it was good enough to up his record to 41-4 and hand Cruz his first loss in 35 fights.

``I felt I was boxing pretty good,'' Mosley said. ``The one thing about the Mexicans is they always come to give you a good fight.''

Mosley and Cruz entered the ring with no idea that Johnson had been injured in the previous fight. Johnson walked from the ring under his own power before collapsing in his dressing room and being taken to University Medical Center.

His promoter, Lou DiBella, said the fighter was undergoing surgery late Saturday night.

``He's not in good shape,'' DiBella said. ``The brain started swelling and they were inducing a coma.''

Johnson took a beating in his fight with Jesus Chavez before the bout was stopped 38 seconds into the 11th round. Johnson had taken about two dozen unanswered punches to the head while on the ropes before referee Tony Weeks finally stepped in to stop it.

Chavez dominated the fight, landing big punches to Johnson's head from the opening bell. Punch stats showed him landing 409 punches to 148 for Johnson.

After the fight at the MGM Grand hotel-casino, Johnson said in the ring that ``I'm all right,'' but later collapsed in his dressing room.
