Jackson injured himself in the third inning of Sunday's game against the Houston Astros while running to first base. Jackson stepped on pitcher Roberto Hernandez's foot and twisted his ankle. He was removed from the game and replaced by Justin Ruggiano. Ruggiano will start in centerfield on Monday night.
Jackson initially hoped he would be able to avoid going on the DL.
"It’s not too bad, hopefully," Jackson said, according to the Tacoma News Tribune. "I’ve sprained my ankle a few times in the past. That kind of helps [give me an idea]. It’s not too swollen. It’s just kind of sore right now."
Jackson was acquired at the trade deadline last season in the deal that sent David Price to the Detroit Tigers. He has played in each of the Mariners' 25 games this season and started 23. He is batting .242 with two home runs and leads the team with five stolen bases.
The Mariners also called up shortstop Chris Taylor and relief pitcher Joe Beimel from Triple A Tacoma.
