Lots to cover from tonight’s practice in Memorial Stadium.

— First off, Nebraska’s players voted for four captains: Linebacker Josh Banderas, center Dylan Utter, wide receiver Jordan Westerkamp and safety Nate Gerry. There will also be a Sam Foltz honorary captain each week, which is something the seniors requested.

— Riley on Gerry, who is suspended for the first game: “All of us, with the team, or on the team, we’ve all had stuff in our lives. Nate made a mistake, doesn’t diminish him as a leader. He’s had a great offseason with this team and they recognized that.”

— Riley on Armstrong not being a captain: “I’ll say I was a little bit surprised, but I know the explanation,” Riley said. “I told the seniors this when we were going to select captains..I told them, there are lots of choices.”

— Linebacker Dedrick Young was out for Saturday’s practice, but Riley said it was a groin injury and he would be fine for Saturday’s game.

— A number of freshmen will definitely play this year: Riley said those players are: cornerback Lamar Jackson, running back Tre Bryant, safety JoJo Domann and punter Caleb Lightbourn.

— Riley said a number of other players will be kept on “redshirt alert” meaning they will continue to practice with the top units, and could play if needed. Those players are: offensive linemen Boe Wilson, Matt Farniok, John Raridon and cornerback Dicaprio Bootle. Riley said freshman wide receiver JD Spielman is right on the cusp of redshirting because of wide receiver depth.

— Freshman safety Tony Butler will redshirt.

— Freshman Quayshon Alexander will undergo shoulder surgery. Riley said they were aware of that coming into the fall.

— Riley said Sam Hahn will be the starting left guard. Corey Whitaker should be returning in the next week or so, but Riley said Hahn has done well to earn that job. Jalin Barnett could continue to be worked in at that position along with Whitaker.

— Nebraska held a brisk walk through on Saturday. About 3,500 UNL students around for a concert by DJ Kool, followed by a fireworks show in Memorial Stadium.
