CHICAGO -- Paul Konerko took some swings in the batting cages before Sunday's series finale with the Rockies. That would be all the action he would see for the day, and possibly a lot longer.
Konerko said he suffered a strain of his intercostals muscles, though he and team trainers weren't 100 percent sure what the injury was.
"I don't know exactly how bad he is right now," White Sox manager Ozzie Guillen said after the game. "But hopefully with [Monday] off, Tuesday they'll see how he feels. You know when you [have] problems with the rib cage, you hope for the best, but I'm not too optimistic about it."
Guillen suggested that Konerko may be placed on the disabled list if the pain persists.
"Most of the times, that happens," Guillen said. "Because that's a real sensitive area, and the one you use the most when you play baseball."
Konerko was at a loss for words about the injury after the game, having been scratched just 20 minutes before game time.
"I've never had anything happen like that," Konerko said. "So I don't really have any answers for you, other than, 'I took a swing and that ended the day. We'll see where it is on Tuesday.'"
Konerko said team trainer Herm Schneider didn't have any instructions for the slugger other than to rest and stay hydrated until Tuesday, when Konerko will be re-evaluated.
