Collins left Friday's practice with what was described afterward as a stinger, reports.

The right tackle also dealt with a minor neck issue last week that didn't ultimately cost him any practice time, but it's not clear if the two injuries are related. Collins didn't play at all last season due to hip surgery, one of a number of injuries that decimated the Cowboys' offensive line, so look for the team to be very cautious with the 28-year-old in an effort to make sure he's ready for Week 1.
