Chicago White Sox left-hander John Danks felt soreness in his shoulder after playing catch Thursday, putting his hopes of returning to the rotation next week in jeopardy, the Chicago Tribune reported Thursday.
Danks hasn't pitched in the major leagues since May 19.

"I obviously didn't expect to feel quite this sore," Danks told the Tribune. "I've never had this before, so I really didn't know what to expect."
Danks threw 61 pitches in a four-inning rehab start for Triple-A Charlotte on Tuesday. He allowed three runs, one earned, on four hits.
"I was just hoping I would bounce back a little better than I have," Danks told the Tribune. "It's part of it, and it's kind of like spring training. You kind of go without throwing; it's going to be sore."
Danks is scheduled to throw a side session Friday, after which it will be determined if he can join the White Sox for next week's series against the Chicago Cubs.
"Everybody has that soreness, but he's the one who knows whether it's that good one, or it's the same thing creeping back up again," White Sox manager Robin Ventura told the Tribune. "He won't pitch if it's one of those where he feels like he did before."
