UPDATE: Actually Dan Johnson isn't in leftfield. Due to travel delays, he didn't arrive at the stadium until around 6:50 so the Rays had to change the lineup, with Ben Zobrist going to centerfield, Eric Hinske to left and Gabe Gross to right.

As for the medical report, it sounds like backup C Shawn Riggans' right knee problem could be serious, due to a possible infection in the bursa sac, and manager Joe Maddon said he absence is "indefinite.'' CF B.J. Upton said his slightly strained left quad felt much better today, and there was a chance he could be available to pinch-hit on Wednesday, though Maddon said it was "possible" Upton's absence from the lineup could extend into the weekend in New York. 3B Evan Longoria was to continue his progression in recovering from a fractured right wrist by hitting flipped balls, but Maddon said he had no update.
