-- There were some injury concerns throughout the day, as several players took precautionary measures during team drills. Linebacker Zach Brown, who strained his quad yesterday, was back on the field but only played a couple of team snaps before sitting out the rest of the day. Other players that held themselves from a full practice were Chris Thompson, Rob Kelley, Ryan Anderson, Daron Payne and Paul Richarson Jr. No word on the extant of any of their injuries, but head coach Jay Gruden will be able to fill the media in on Saturday.

-- Gruden talked extensively about the running backs group at his morning press conference, admiring the depth chart and the multiplicity of options he has each day at practice. He did mention specifically the need for a third-down type backup to Chris Thompson, of which the Redskins have several to choose. Byron Marshall is one of those players, and he got the first couple of snaps Friday. The third unit offense got more work in the early portion of practice, too, so that meant Martez Carter and Kapri Bibbs got a handful of handoffs as well. All three have the ability to escape defenders, and Bibbs believes that by the end of the preseason, every one of them should be on an NFL roster.
