ALLEN PARK — It wouldn’t be NFL training camp without a couple injuries.

Lions left tackle Jeff Backus and running back Mikel Leshoure were sidelined during Saturday’s training camp session.

Backus injured his thumb during one-on-ones and went inside for X-rays. He returned to the field, but not to action.

“We’re going to wait and see. It wasn’t real determinant right away (on the X-rays), but there were some findings on it so we’ll look at it later this afternoon,’’ coach Jim Schwartz said.

An offensive lineman could play with a broken thumb, but no sense to push it on second day of camp.

Leshoure made it until deep in the practice when he grabbed his hamstring.

Schwartz was uncertain of the severity.

“I’ll be good, I’m fine, I’m straight,’’ said Leshoure who is coming off Achilles’ tendon surgery.

Rookie defensive end Ronnell Lewis, who missed Friday’s opening session with a tight back, was back at work on Saturday.

Jahvid Best, Ryan Broyles, Jonathan Scott and Chris Greenwood remained out.
