The Chicago Cubs placed right-hander Jameson Taillon on the 15-day injured list Friday with a right calf strain.
Manager Craig Counsell told reporters he expects Taillon to be sidelined for more than a month for an injury that occurred during a between-start workout.
The IL designation is retroactive to Tuesday.
Taillon, 33, is 0-3 with a 10.66 ERA in his last three starts, allowing six home runs in 12 2/3 innings. For the season, Taillon is 7-6 with a 4.44 ERA in 17 starts.
Chicago recalled left-hander Jordan Wicks from Triple-A Iowa in a corresponding move.
Wicks, 25, made two appearances out of the Cubs’ bullpen in April and went 0-1 with a 13.50 ERA. He made 11 of his 12 appearances at Iowa as a starter, going 1-3 with a 4.06 ERA.
