"Honestly, it happened and I didn't know what to think," Franklin said. "I definitely didn't feel great, but I felt weird for a second. But other than that, once the trainer got there, he told me to relax and stay still."
The injury proved to be not as severe as it appeared, and Franklin was able to remain in the game, hitting an RBI double later in the inning.
"I can feel it but nothing really outrageous or anything out of the normal," Franklin said before Monday's game.
Manager Eric Wedge confirmed that Franklin could have started Sunday's game, but that it made sense to rest him while also giving Dustin Ackley time at second base to balance the lineup against lefty Matt Moore. Franklin did enter the game as a pinch-hitter, striking out.
