Norris will throw in the bullpen one more time on Wednesday before being sent out on rehab. Norris, 27, injured his hip flexor on May 31 against the Rockies, and wasn't the same as he dealt with leg and knee problems. He was 5-1 with a 3.34 ERA in his first 10 starts of the season, but just 0-3 with a 13.09 ERA in his next three starts.
Manager Brad Mills on Tuesday provided updates on some of the Astros' other ailing bodies.
Outfielder Fernando Martinez (concussion) took batting practice on Tuesday and was given more post-concussions tests. Mills said Martinez is scheduled for even more tests with a doctor on Wednesday, with hopes he'll begin a Minor League rehab assignment on Thursday.
Outfielder Travis Buck (right Achilles' tendinitis) went 0-for-2 in his first rehab game on Monday for Double-A Corpus Christi at San Antonio. Mills said Buck ran well and is progressing. Buck will play two or three games with Corpus Christi and three or four with Oklahoma City.
Infielder Marwin Gonzalez (bruised right heel) took batting practice on Tuesday, but isn't quite ready for a game setting. "He's still sensitive to the touch, which enables him to go out there and do some work defensively, but at the same time he's not able to do everything," Mills said. Once Gonzalez is pain free, he'll be sent out.
Right-hander Kyle Weiland, who made three starts for the Astros in April before an infection sidelined him indefinitely, had his peripherally inserted central catheter line removed recently and lost weight during his recovery. Mills said Weiland needs to build up his strength and muscle density before he can do anything. "It's going to be a long process," Mills said.
