TORONTO (Reuters) - Chicago White Sox slugger Adam Dunn was expected to be sidelined for his team's next five games after undergoing an emergency appendectomy, the Major League Baseball club said on Wednesday.

Dunn went under the surgeon's knife at a Kansas City hospital on Tuesday night after complaining of abdominal pain.

The 31-year-old designated hitter came through the operation so well that he asked the White Sox if he could play as early as Thursday.

"I talked to him this morning and he wants to play," White Sox manager Ozzie Guillen said on Wednesday. "But I don't want to take the risk."

Dunn, who signed a four-year $56 million deal with the White Sox during the offseason, was the second major leaguer in less than a week to undergo an appendectomy.

St. Louis Cardinals outfielder Matt Holliday had the same operation last Friday following an opening day loss to the San Diego Padres.
