"I've had several conversations with him and the doctors," said general manager Jack Zduriencik. "We expect a complete recovery. What he needs to do is stay home for the next short period of time. We expect him to be back sooner than later. He sounds normal, talking to him it sounds like everything is fine and he's ready to roll. But we're going to err on the side of caution.
"The common-sense thing is to have Eric rest, and it makes sense that he won't make this trip to the East Coast," Zduriencik said. "When we get back, he'll be evaluated and we'll see where we stand."
Bench coach Robby Thompson has filled in for the past three games since Wedge was helped from the field after becoming dizzy during batting practice before Monday's game. He'll continue to serve as the interim manager in Wedge's absence.
"Robby will handle the club baseball-wise," Zduriencik said. "We have great confidence in what he can do. He's obviously one of Eric's lieutenants, and I'm happy he's going to have this opportunity. He's a good guy to turn this club over to and we'll all be in communication and get back on a roll tomorrow."
