Injuries: Sam Bradford (knee) limited in Vikes' practice

Ezekiel Elliott popped up on the Dallas Cowboys' injury report Wednesday, but the issue shouldn't hinder the running back.

Elliott is dealing with bruised ribs after taking a hit in Sunday's loss to the Rams but is fine, coach Jason Garrett told reporters Thursday, via NFL Network's Jane Slater.

The running back practiced fully on Wednesday and isn't expected to be hampered in the Week 5 showdown with the Green Bay Packers.

One injury the Cowboys are monitoring closely is Tyron Smith's back. The left tackle is not practicing with back tightness. The hope is to get Smith back at practice on Friday and have him ready for Sunday's game. If Smith can't play, Byron Bell would start at left tackle, per Garrett.

Garrett also confirmed defensive end Charles Tapper broke his foot during a pass rush drill at practice and will require surgery. Tapper is out 8-10 weeks. The team placed him on injured reserve later Thursday.

One positive note: Cowboys corner Nolan Carroll practiced yesterday for the first time since entering concussion protocol.
