Assuming Kentucky Derby winner Animal Kingdom is healthy, he will definitely run in the Preakness on May 21 in Baltimore, trainer Graham Motion said this morning.

"I think we'd better, right?" joked Motion, who trains horses in Fair Hill, Md. "I mean I'm going to the Preakness as long as he's OK. He won the Derby. We're going."

Motion said he expects Animal Kingdom will fly back to Maryland on Tuesday, and arrive in the late afternoon.

Animal Kingdom, at 20-1 odds, won Saturday's Derby by roaring from the pack to chase down the race leaders. It was his first race on a dirt track.

Apparently, Pimlico Race Course will be his second.
