Redskins.com's Jake Kring-Schreifels breaks down the key plays and highlights from Day 2 of the Washington Redskins' 2018 training camp in Richmond, Va.

Offense:

-- 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.

-- Watching more of Derrius Guice, the Redskins seem to like using him as a pass catcher in the flat, where he has more room to operate and make the first defender miss. Even as he finishes plays and sprints upfield, he's very cognizant of never running out of bounds. As a defensive back approaches, he purposefully spins or cuts back inside to get more yardage, little habits that indicate his physical style and aggressiveness to reach for more.

-- Trent Williams and Morgan Moses got in some team reps during the second session just briefly. It's a small dose, but a good sign as they become more integrated into the offense. Jordan Reed is still just working during the 1-on-1 and 7-on-7 drills, trying to get some timing down against defensive backs. Now that the route running feels comfortable for him, he begins the process of adjusting to new quarterbacks and having a corner or safety in front of him.

-- Josh Doctson and Brian Quick have both shown off their ability to high-point the football, and their footwork looks espcially crisp. Doctson made an impressive grab over new cornerback Prince Charles Iworah during the early stages of practice.

Defense:

-- The second day belonged to the defense, primarily the secondary. It began with safety D.J. Swearinger, who from the start seemed on top of his game, making checks at the line of scrimmage, earning praise for his talk from Coach Torrian Gray. Later during team drills, Swearinger cut through the crowded middle of the defense and picked off Smith, scooping up a low throw intended towards Richardson. Not long after, he nearly had another interception. "Stop playing with me," he yelled in his standard gravel-toned excitement, proceeding to dap up nearly every defensive back he could find.

-- That enthusiasm spread to the rest of the secondary, too. Rookie Greg Stroman committed two nice pass defenses – one on a slant route covering Trey Quinn, the other a batted ball to Robert Davis by the sideline – while Josh Norman nearly grabbed an interception on a pass intended for Josh Doctson on a comeback route. Fabian Moreau, Quinton Dunbar and Orlando Scandrick all got in on the incompletion momentum near the end of practice.

-- While it's not a true test of offensive line play, the 1-on-1 portions that feature defensive linemen attacking tackles, guards and centers are still intriguing to watch. On Friday, Anthony Lanier II seemed the most dominant in getting after the quarterback, and it's clear why Daron Payne already seems like a veteran. His power up the middle, coupled with a spin move he put on during his third rep, showed some of the versatility he brings to the line. Backup tackles Ty Nsekhe and T.J. Clemmings seemed to have their way though, sizing up some of the younger linemen.

-- Because Jim Tomsula believes in a meritocratic practice, it's not yet clear what a rotation past Matt Ioannidis, Payne and Jonathan Allen would look like, but Lanier and Tim Settle got some more opportunities together against the first string offensive line and pushed the pocket well. Saturday, when the players put pads on, should provide a better sense of how the pocket collapses and how much time the secondary has to work with. After today, it seems like not too much.

Special Teams:

-- After some extensive work on punt returns, the Redskins closed practice with the field goal unit. Kicker Dustin Hopkins made all five field goal attempts, from 33, 35, 38, 40 and 43 yards away, respectively.
