ALLEN PARK -- Detroit Lions left tackle Jeff Backus and running back Mikel Leshoure sustained injuries on the second day of training camp.

Backus left practice with an injured thumb, while Leshoure sustained a hamstring injury.



Lions coach Jim Schwartz was unsure of the severity of Backus' injury, but planned to consult with the team's medical staff later this afternoon, which likely means there is some sort of significant damage.

"He hurt his thumb in one-on-one," Schwartz said. "Went in and got x-rays. Didn't return to practice. We're going to wait and see what those looks like. It wasn't real determinate right away, but there's some findings on there, so we'll look at it later this afternoon.

"We'll see what comes of it. If it's something long-term, we'll let you know."

Backus, who is an 11-year veteran, has started in all started all 177 games since the Lions used their 2001 first-round pick on the University of Michigan offensive lineman.

As a result of Backus' injury, Lions tackle Corey Hilliard started on the left side, while rookie Riley Reiff and Jason Fox primarily ran with the second and third teams.

Schwartz said even if Backus' thumb is broken, the left tackle could play with that injury.

"Guys have played with a lot worse, but obviously, it's a training camp practice practice, we're not going to push through a situation like that," Schwartz said. "We'll just wait and see."

In addition, Leshoure stopped practice after sustaining a hamstring injury. His status is day-to-day.

"He grabbed his hamstring a little bit," Schwartz said. "Where it turns out to be, we'll see, but again, if it's long-term, we'll let you know. Don't know."
