The Astros placed Javier on the 15-day injured list Monday, retroactive to May 24, due to right forearm discomfort.
Javier was scheduled for a bullpen session Sunday, but he was pulled after experiencing discomfort in his right forearm. He'll be sent for imaging Tuesday to determine the extent of the injury, per Brian McTaggart of MLB.com. With Javier on the IL, Hunter Brown will start Tuesday against the Mariners, while Justin Verlander and Spencer Arrighetti take the mound Wednesday and Thursday, respectively, per Matt Kawahara of the Houston Chronicle. The Astros recalled right-hander Alex Speas from Triple-A Sugar Land in a corresponding move.
