Norris exited the Detroit Tigers' 5-3 loss to the Cleveland Indians on Monday with a right oblique strain, re-aggravating the same muscle he injured last fall diving for a ground ball in the second inning off the bat of Abraham Almonte.
"It just kind of grabbed at me," Norris told the Detroit Free Press. "I went back in and just kind of checked it out, and went out for the third and I just couldn't really finish my pitches. I kept grabbing it, so they pulled me in."
The Tigers placed the former Science Hill player on the 15-day disabled list after an MRI on Tuesday revealed the grade-1 strain.
Norris said it doesn't feel as bad as last year, but results for that injury came back more serious than originally expected too.
"I felt like maybe I could have gone on, but it was obvious in my delivery that it was kind bothering me," Norris said. "They just want to take care of me."
The injury marks another setback for Norris, who worked his way back from a non-displaced fracture in his lower back in spring training. Monday was the left-hander's third start of the season.
"I don't even know what to think at this point," Norris said. "But I'll wake up tomorrow and get ready for that day."
Norris lasted just over two innings against the Indians, leaving early in the third. He allowed three hits, two earned runs and a walk along with three strikeouts. He threw 31 pitches and worked his way out of a two-on, no-out jam, stranding runners on second and third in the second inning.
“He looked pretty good overall,” Detroit manager Brad Ausmus said.
Ausmus said Norris is expected to miss 10-14 days.
Norris, 23, has allowed seven runs on 17 hits in 13 innings this season. Monday was Norris' fourth appearance, including his third start, of the season. He owns a 4.85 ERA, 16 strikeouts and three walks. The no-decision Monday left him with a 1-0 record.
Right-handed reliever Buck Farmer was recalled prior to Detroit's game Tuesday against the Indians, the second in a three-game series at Progressive Field.
The Tigers are now without two starting pitchers for their four-game series at Toronto that starts Thursday.
On Monday, Jordan Zimmermann (9-4, 3.95 ERA) was placed on the 15-day disabled list with a strain in the right side of his neck. Zimmermann was scheduled to start Tuesday against the Indians. Anibal Sanchez started in his place.
Sanchez would be in line to start Sunday in Toronto, too.
Farmer will be on his fifth separate stint with the Tigers this season, having posted a 1-4 record with a 6.42 ERA and 1.62 WHIP in 10 starts in Toledo. He has a 2.70 ERA with a 1.13 WHIP in nine relief appearances with Detroit.
"It's obviously never good, but I know (Jordan's) going to work hard to get back and I'm going to work harder than ever to get back," Norris said. "If I have to miss some time, I'm thinking positive right now, but we're all fighters here."
