Ravens safety Tom Zbikowski had a first-round knockout of Blake Warner on Saturday night, improving his record to 4-0, the Baltimore Sun reports.

A right uppercut at the 2:20 mark in the fight against 33-year-old Warner (1-3) forced referee Vic Drakulich to put an end to the match without making a count. Zbikowski's win marks the third fight he's won by first-round knockouts.

“This was my best win since coming back from a five-year layoff,” Zbikowski told The Daily Oklahoman. “I felt composed and relaxed out there.”

Zbikowski is scheduled to fight again on May 21 in Cabazon, Calif., and on June 4 at Los Angeles' Staples Center.
