General manager Dayton Moore said that Dyson, playing for Caracas, will take a couple of weeks to heal from a contusion and slight strain of the shoulder. He is not likely to return to Venezuela, where he was batting .227 (5-for-22) in seven games.
"He was tracking a ball and ran into a wall while chasing a deep foul. He's fine," Moore said.
