Philip Humber, who was hit in the forehead by a ball off the bat of Kosuke Fukudome in the White Sox game against the Cleveland Indians on Thursday, was placed on the 15-day disabled list after being re-evaluated on Friday.
The Sox purchased the contract of right-hander Josh Kinney from AAA Charlotte to take Humber's place.
Kinney, 32, is 6-3 with a 2.77 ERA over 61 2/3 innings in a team-high 49 relief appearances. Kinney has pitched in 45 major-league games with St. Louis, going 1-0 with a 4.56 ERA for the Cardinals in 2006, 2008 and 2009.
Humber (8-8, 3.63) appeared to be OK after the liner hit him flush above his right eye and spoke with reporters after the game. He was taken out immediately for precautionary reasons. Initial tests checked out OK. The Sox described his injury Friday as a facial contusion.
Right-hander Zach Stewart, who came in for Humber in the second inning, is a possbile replacement in Wednesday's start at Anaheim for Humber.
"Of course, everyone was asking if I was OK,'' Humber said. "I told them I was good, I felt like I could still pitch and wanted to be out there. But at the same time, they got a job to do and take every precaution that there wasn't anything serious going on. I think we'll re-evaluate [Friday] and see where we're at. As of right now, I feel good. I feel like I just got a little pop knot on my forehead. Other than that, I feel very fortunate.''
Humber did not get a glove on the ball, and fell backward bent at his knees.
"I saw it, but a little late,'' he said. "I wasn't as quick as I thought. But I was very fortunate and one thing I would like to say is that my wife was here, so obviously upsetting for her. But she told me the fans were very supportive and had a lot of kind things to say to her, so I appreciate that."
"First you're kind of dazed, what just happened. But I wanted to make sure I got up, just in case we might get an out. But at the same time, I knew Kristan was in the stands and I didn't want her to think it's worse than what it was. That's what was on my mind."
