Yankees left-hander A.J. Burnett hit him with a 93-mph fastball when he squared to bunt. Victorino said Burnett apologized, and added that it wasn't retaliation for the Phillies hitting Alex Rodriguez with pitches three times this series.
Victorino stayed in the game, but he took X-rays a short time later.
Victorino and Phillies general manager Ruben Amaro Jr. said X-rays were negative and he had a bruise. Ben Francisco replaced Victorino in the field in the eighth inning because Victorino said he had increased swelling in the finger as the game wore on.
He said he could throw, but he struggled to hold the bat.
"Hitting was a little difficult," he said. "I couldn't find my grip. But I don't want to make any excuses for me stinking it up."
Victorino, who was 0-for-3 with a run scored, expects to be in the lineup Wednesday in Game 6 at Yankee Stadium.
