Reyes had been out since June 10 because of right shoulder tendinitis. Tampa Bay manager Joe Maddon said there no limitations on Reyes.
Also, closer Troy Percival, sidelined since July 1 due to a left hamstring strain, was scheduled to be re-examined Friday night. It is possible the right-hander could return within the next few days.
Shortstop Jason Bartlett, out with a right knee strain, is working out and might be back early next week.
Left-hander Scott Kazmir, who got the win in Tuesday's All-Star game by pitching a scoreless 15th inning, will start Monday night's game against Oakland after the Rays decided to give him an additional day off.
