Jackson played center field in the top of the first inning and made a catch on a fly ball to record the first out of the game. But he returned to the dugout after the top of the inning clutching his back and walking gingerly. Jackson left the dugout and went to the clubhouse with head athletic trainer Kevin Rand.
"It was a shocker," Tigers manager Jim Leyland said. "I thought he caught the ball kind of funny on the first play of the game. It looked like something wasn't just right. I wasn't aware of anything until he came up to hit and said he had back spasms. Kevin said he wasn't going to be able to go."
Don Kelly shifted from left field to center and Ryan Raburn entered the game in left field and took Jackson's spot as the leadoff hitter. Raburn went 0-for-4 on the afternoon.
The Tigers have Monday off, giving Jackson an extra day to heal before the they open a three-game series against the Nationals.
