Johnson, 38, is currently on disabled list because of a left foot injury, which occurred in April. He is also dealing with a broken rib, which was caused by an errant throw by the opposing third baseman. It's not known if Johnson will play another game this season. It will take about a month for the broken rib to heal.
Johnson played in only 12 games this season and went 4-for-18 with two RBIs.
