It was announced as a mild strain, and manager Joe Maddon said a conservative estimation was that Fuld would miss at least a couple days' action.
Fuld said after the game that he had tweaked the hamstring on Friday night at Yankee Stadium, and that he had been playing through it for most of the weekend. He hit a grounder to second base on Sunday that New York's Robinson Cano misplayed initially before throwing him out, and Fuld grabbed his right leg as he neared the bag.
"Just kinda tweaked it a little bit a couple nights ago," Fuld said. "First night here. Just kind of thought I could play through it. I kind of felt it throughout the day, at different points of the game. But definitely, when I saw Cano bobble it, I tried to turn it up a notch, and that's when I grabbed it."
Fuld was 0-for-2 on the day and left with the Rays behind by a score of 6-1. Tampa Bay eventually lost, 6-4.
"It feels all right," Fuld said. "It's not too bad, I don't think. I don't have any history with hamstrings, so it's hard to know anything, but I've been walking on it pretty well at this point. It's hard to know how severe it is at this point."
Ben Francisco replaced Fuld in right field and in the No. 8 spot in the lineup. Francisco doubled in the eighth inning.
