Hill was diagnosed with a shoulder contusion following his removal from Wednesday's game against the Nationals, Lochlahn March of The Philadelphia Inquirer reports.
Hill collided with the center-field wall while trying to make a diving catch in the 11th inning. His shoulder appears to have taken most of the damage, though interim manager Don Mattingly said after the game that the team still has some tests to run on Hill and will know more about his health before Thursday's series finale versus Washington.
