Cynthia "C.J." Ross told The Associated Press on Wednesday that she'll take time away from judging fights.
The 64-year-old Ross lives outside Las Vegas. She's been judging fights for 22 years.
She scored Saturday's 152-pound title fight at the MGM Grand Garden Arena a 114-114 draw, but Mayweather won a majority decision after two other judges scored him the clear winner.
Nevada boxing regulators generally backed Ross, although state Athletic Commission Chairman Bill Brady told reporters the panel could have looked more closely at Ross' selection before the Mayweather-Alvarez fight.
