Phillies general manager Ruben Amaro Jr. addressed the health of Roy Halladay, Ryan Howard and Chase Utley on Thursday night. Philadelphia placed Halladay on the 15-day disabled list on Tuesday with a strained right latissimus dorsi. He will be sidelined from baseball activities for three weeks and is expected to be out from six to eight weeks. "We'll probably know more, hopefully we'll have an update for you guys [on Friday] once we get all the information," Amaro said. "We don't anticipate a whole lot of a difference, but of course you always get nervous about what other doctors may say about his situation. But we feel pretty confident that it will be a situation where we don't have to worry about any surgeries. I hope." As for Chase Utley and Ryan Howard, Amaro said the two are progressing each day, though there is still no timetable for either to return. Asked on Wednesday in New York if Howard is likely to return before July 1, Amaro said, "I don't expect it." "I know that Ryan does a little bit more each day, and I know that Chase has been feeling better and better, I think, every day," he said on Thursday. "It's one day at a time. It's a process, but hopefully we can get those guys playing in games sometime soon."
