Nationals left fielder Bryce Harper was diagnosed with a bruised left side after coming out of Wednesday's game early, according to Comcast Sportsnet. Harper initially suffered the injury after colliding with the outfield wall in Tuesday's game, then appeared to aggravate the injury on a check swing Wednesday.
Harper, who is hitting .337 on the year after going 0 for 2 with a walk and a run Wednesday, is day to day.
