Phillies GM Ruben Amaro expects Chase Utley (concussion) to sit out at least through the end of the team's road trip, which concludes on September 14. We knew Utley would sit out this weekend, but evidently he'll be held out for at least an additional series, as well. "He's going to be re-examined on Saturday," Amaro said. "If the test goes well, he could go ahead and meet the team in Houston on Monday. But I don't expect him to play the next two series just so we can be cautious. That's my guess." Amaro added that the second baseman might also sit out next Thursday's doubleheader against the Marlins. "It's very mild, we think it's very slight, but it's a concussion nonetheless," Amaro said. "Chase is already feeling better. He's getting some rest. We'll know more Saturday."
