Dallas Keuchel will undergo tests on his sore shoulder and miss at least his next two starts.

"Dallas flew back to Houston to get further evaluated," A.J. Hinch said. "He played catch in Texas the last day and didn't feel great, so he flew back to see our doctors, had some tests. He's been diagnosed with shoulder inflammation, which we knew.

"It just hasn't resolved, and he hasn't been able to play catch, so we're going to shut him down for the time being. He won't make tomorrow's start. He won't make his start this weekend, either. We'll get back to Houston and evaluate what's next for him, but he went back to Houston."

Keuchel had been slated to start Friday against the Texas Rangers. There is some doubt as to whether he'll start again this season.

"We'll have to get back and see how all these tests come back and how he continues to feel," he said. "We tried to give him some gaps in time and give him some rest period, but that hasn't solved it. He's going to go see the doctors he needs to see, and until he's pain free, he's not throwing. Where we are in the calendar is going to bring the obvious questions, but we just don't know right now."
