The former New York Yankees outfielder apparently injured his quad playing for Carolina in Puerto Rico, according to the New York Journal News. The 40-year-old Williams is trying to get in shape to compete for Puerto Rico in the World Baseball Classic in March.
Williams went 1-for-3 for Carolina in his Winter League debut on Dec. 22. The five-time All-Star was the designated hitter in his first game since 2006. He has been hitless in two games since then, and Williams' last game was Dec. 26, when he went 0-for-1.
In September, Williams appeared in uniform at Yankee Stadium for a pregame ceremony before the Yankees' final home game. He has concentrated on his music career since leaving the team in 2006 and is set to release his second album in April.
