Red Sox OF Jackson leaves game

Boston Red Sox outfielder Conor Jackson left Sunday's game against the Texas Rangers in the fourth inning.

Jackson, acquired from Oakland at the August 31 deadline, suffered an apparent arm injury when crashing into the low padded wall in right-center field while trying to track down an Ian Kinsler hit in the third inning.

Kinsler eventually tripled, while Jackson was lifted from the game for Darnell McDonald.
