CHICAGO -- The strained right oblique muscle that cost Adam Dunn two games in the Detroit series last weekend at Comerica Park knocked the slugger from the lineup for Friday's series opener against the Royals. Manager Robin Ventura said that Dunn aggravated the injury during Wednesday's victory over the Twins and it's not known how long he will be out of action.
"Just trying to care of it and make sure nothing gets worse," said Ventura of Dunn, who ranks second in the Majors behind Josh Hamilton with 38 homers. "It's just one of those that keeps coming back every once in a while.
"I'm hoping just today or tomorrow. You never know. It's just one of those, it's in a bad [spot]. I guess any time a hitter has it in his rib area, you can probably [re-injure] it every day."
Kevin Youkilis was also out of Friday's lineup. The veteran third baseman flew home to be with his wife, Julie, for the birth of their child. Ventura hopes to have Youkilis back Sunday.
Jose Lopez started at third, Dewayne Wise in left field and Dayan Viciedo at designated hitter Friday to make up for the two absences.
