"After the second opinion, they decided the best thing he could do was rest it entirely for another two weeks because of the inflammation in the elbow," manager Trey Hillman said.
Hillman said the elbow inflammation was causing the discomfort in the forearm, which has bothered Aviles since Spring Training. Aviles was examined this week by specialist Dr. Lewis Yocum in Los Angeles and underwent an MRI.
Aviles went on the 15-day disabled list May 23 and is undergoing rehabilitation treatment at Surprise, Ariz. At the end of two weeks, he will be re-evaluated.
Tony Pena Jr., who returned from the DL to play the first two games of the Tampa Bay series at shortstop, was given a break Thursday. Willie Bloomquist instead played shortstop.
Hillman said Pena, coming back from hand surgery, had normal soreness, and he didn't want him to overdo it by playing a third straight game.
