Jones texted MLB.com saying that he cramped up during his second at-bat, but he expects to be ready to play in Saturday's game. He received fluids in the club's training room and believes it is nothing serious.
"It was just sore," Jones said. "Let [Lou] Montanez go out there, and he got a knock. He had a fresh pair of legs, so no need for me to try and strain myself."
Jones put Baltimore on the scoreboard in the second inning with his fourth homer of the year, a two-run shot off Washington starter Scott Olsen's first pitch. He walked in his second plate appearance in the third.
Left fielder Corey Patterson assumed center field duties in Jones' absence, with Montanez filling in at the corner outfield spot.
At the time of the injury, Jones was batting .254 with 12 RBIs.
