Royals catcher Salvador Perez is expected to be out seven to 10 days with a bruised left thigh after colliding with rookie third baseman Cheslor Cuthbert while catching a foul popup on Saturday.

Perez's MRI confirmed the injury was a contusion and there was no structural damage.

"Hopefully it's not going to require a trip to the DL," Royals manager Ned Yost said Sunday. "We're hoping he'll be back in seven to 10 days. It could be earlier or later. We'll just have to wait and see and just manage it day to day."
