CLEVELAND -- Indians left-hander Boone Logan will miss significant time after being placed on the 10-day disabled list with a strained muscle in his back, manager Terry Francona said Friday.
Logan fell to the ground and grabbed his left shoulder after throwing a pitch Thursday against San Francisco. He was examined by a team trainer and walked to the dugout with a lat muscle injury. Logan underwent tests by Indians doctors and will seek a second opinion.
"He's going to be down for a while," Francona said of Logan, who is 1-0 with a 4.71 ERA in 38 appearances.
The injury is the latest to hit Cleveland's pitching staff. Right-hander Corey Kluber is expected to start Sunday against Toronto after his scheduled outing Friday was pushed back because of a stiff neck. The Indians' ace missed a month earlier this season with a back injury.
Danny Salazar, who hasn't pitched since June 3 because of a sore right shoulder, will be activated from the DL and start Saturday. He's 3-5 with a 5.40 ERA in 12 games (10 starts).
Left-hander Tyler Olson was recalled from Triple-A Columbus to take Logan's roster spot.
The slumping Indians have lost six of seven.
