Paul Konerko surgery Thursday

Chicago White Sox first baseman Paul Konerko will undergo surgery on Thursday to remove a floating particle between his left hand and wrist, Konerko said Tuesday.

"I was going to have it the day after the season or the day after the playoffs," Konerko said. "It was going to be as quick as we could whenever the season ended."

It's the second procedure Konerko has had on the hand/wrist this year, and he also had one last season. Konerko, who said he has had the fragment since 2009, missed two games last season because of soreness, and then had a fragment dislodged in May and missed two games.

This procedure will remove the particle and is expected to last 20 minutes. The recovery time is likely four to six weeks.

"It was not a factor in (his swing in) any way other than in early May after I had that procedure done it hung around a little longer," Konerko said. "At that time, we were playing the Dodgers and Cardinals so, it wasn't a good time then. I really never had surgery before other than that. I have no reservations about my wrist in the future."

Konerko was not in the lineup on Tuesday against the Cleveland Indians. The season finale is Wednesday.
