Konerko ready to begin light exercises

TORONTO -- White Sox first baseman Paul Konerko checked out fine after undergoing a concussion-related exam at Rush University Medical Center in Chicago on Monday.

Konerko, who sustained the concussion against the Royals on Tuesday, is progressing well and will start doing some light physical activity as early as Tuesday.

White Sox manager Robin Ventura said the plan is for Konerko to start riding a stationary bike and incorporate some running but doesn't expect him to start doing any baseball activities other than take grounders and maybe play catch until later in the week.

"I would imagine once he starts doing baseball stuff, [the doctors] will check him to make sure [the concussion symptoms] go away," Ventura said. "Right now, it's slow stuff. Most of it is just rest."

Konerko, who did not travel with the team to Toronto, is eligible to come off the seven-day disabled list Friday when the White Sox are in Kansas City. Ventura said everything would have to be perfect for that to happen and that it's too early to tell if that scenario is likely.

"It's just more of how he feels," Ventura explained. "You have seen some guys, it takes them a long time to get back and some guys where it hasn't taken that long. Gotta cross your fingers, hoping it's Friday."

While Chicago will certainly miss Konerko's middle-of-the-order production, Ventura said his leadership qualities in the clubhouse cannot be overstated.

The skipper described Konerko as a lead-by-example type of player, rather than a vocal leader, but said he still commands the attention of his teammates

"When people think about the White Sox, he's going to be the first thing you think of because of his tenure, stature on the team and the way he does things," Ventura said. "He does things the right way.

"There is just the example he sets on how guys act, prepare and play the game."

In 101 games, Konerko is batting .316, with 18 homers 54 RBIs and an .892 OPS.

Youkilis back in lineup against Toronto

TORONTO -- Kevin Youkilis was back in the White Sox lineup for Monday's series opener against the Blue Jays, batting second and playing third base.

Youkilis was forced to miss Sunday's contest after getting hit in the forearm with a pitch from Oakland's Grant Balfour in the ninth inning of a loss Saturday.

The veteran has also been battling a sore right knee, but told skipper Robin Ventura when he arrived at the ballpark Monday that he was ready to go.

"He's good, he said he was fine," Ventura said. "I think it helped for him to get a little break."

In 38 games with the White Sox since being acquired from Boston, Youkilis is batting .252 with 10 homers, 29 RBIs and an .875 OPS.

Youkilis struggled over his 42 games with Boston, hitting just four home runs while driving in 14, but has been a major boost to the White Sox.

Worth noting

White Sox manager Robin Ventura gave Tyler Flowers the start behind the plate for Monday's series opener, with A.J. Pierzynski slotted as the designated hitter and Adam Dunn filling in for Paul Konerko at first base.

Ventura said it was a way to give Pierzynski some rest behind the plate. The skipper plans to start Pierzynski at catcher on Tuesday and Wednesday and said he would likely go back to Flowers for Thursday's finale.
