Astros reliever Jose Cisnero returned to Houston and was examined by a team doctor on Thursday after experiencing discomfort in his elbow, MLB.com reports. Cisnero experienced the discomfort Tuesday against the Tigers. He game up two runs in an inning of work during that outing.

"He had some discomfort, and so we let him come in the next day and get evaluated and we felt we needed to have him see our doctors and we sent him here," general manager Jeff Luhnow said.
