KANSAS CITY, Mo. — Royals All-Star 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.

Perez was hurt Saturday and an MRI confirmed the injury was a contusion and there did not appear to be 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.

"Great news, you don't want to have to put him on the DL and he's ready to play in eight days and has to sit there for another week."

Kansas City recalled catcher Tony Cruz from Triple-A Omaha, where he was hitting .278 with three home runs and 20 RBIs in 31 games. Cruz had a .220 average in 229 games with St. Louis during the past five years.

The Royals optioned right-hander Peter Moylan to Omaha. Moylan went 2-0 with a 2.45 ERA in six relief appearances. The Royals will try to go with 12 pitchers until Perez returns.

"If I get in a pitching jam, I'm going to have to do something," Yost said. "But we're right now we're trying to stay away from that and go with 12 pitchers. I'm hoping we can."

Perez had called for the ball when Cuthbert barrelled into him.

"We've been kidding him about it," Yost said. "I told him (Chiefs coach) Andy Reid called and wants him to be on the special teams, but Andy was afraid he was going to tackle the guy when he's giving the fair catch sign. I kind of dropped that one on him."
