Martinez left Sunday's 5-1 win at San Francisco and was replaced by Jason Varitek.
The Red Sox did not say whether Martinez will go on the disabled list. He will be re-evaluated on Monday's off-day.
Boston is already missing star second baseman Dustin Pedroia, who recently broke his left foot.

Oddsmakers from online sports book Sports Interaction currently list the Red Sox at 17/2 to win the 2010 World Series. Boston is also 4/1 to win the American League Pennant.
