"He was battling it a little bit right after batting practice," manager Buck Showalter said. "After he threw up, he seemed to be feeling a lot better and had cleared up, and then got a little worse after he ran the bases a lot and had to get him out of there. They took him over to check him a little further and make sure it's not something else. We'll see."
Jones, who returned to the lineup Thursday in Texas, grounded out in the bottom of the sixth inning against Toronto starter Marcus Stroman. He was replaced in the top of the seventh by Joey Rickard, who moved over from left field and had Nolan Reimold take his spot.
Jones entered Tuesday batting .208 with a homer and five RBIs.
