Cowboys' Ryan Switzer Returns to Practice Posted Aug 23, 2017 Dallas Cowboys receiver Ryan Switzer was a limited participant in Monday's practice. Switzer has missed all three of the Cowboys' preseason games after suffering a hamstring injury in late July. The rookie fourth-round pick was expected to challenge for the punt return job, but may have a lot of ground to make up in the competition due to all the time he's missed. (CBS Sports)
