UPDATE, 8:52: C Dioner Navarro felt well and looked good enough in Thursday's workout that the Rays expect him to be ready to play on Friday, and if so they will option John Jaso back to Triple-A. Navarro said he was ready to go.

NEWS: The Rays have reassembled in Kansas City for  workout tonight, though their five All-Stars are excused.

The Rays are unsure about the health of two starters, as C Dioner Navarro will be evaluated after tonight's workout to see if he is ready to play for the first time since being struck in the mask by a ball on Saturday. Triple-A C John Jaso is here in K.C. as well in case Navarro isn't ready and needs to go on the DL.

The Rays won't know until Friday afternoon if 3B Evan Longoria will be able to play, manager Joe Maddon said. Longoria's right ring finger infection is healing, but Maddon said it is "probably a solid 50-50, maybe  60-40" Longoria will play Friday but if not he will be ready to go on Saturday. Longoria had not made it back from Los Angeles, where he attended the ESPY awards, so the team medical staff had not had a chance to see him yet.

RHP Grant Balfour, who was put on the bereavement list as he went to Australia for a funeral, is expected to be back Friday though Maddon said he may not want to use him after the long trip. The Rays used Balfour's roster spot to bring up Jaso.
