Husker coach Bo Pelini confirmed that sophomore offensive lineman Tyler Moore has not been at practice the past couple days.
Whether the left tackle is coming back to the program remains unknown.
"Tyler Moore has left the team temporarily," Pelini said following Saturday's scrimmage at Memorial Stadium. "We'll see where that goes. I'm not exactly sure if that's going to be permanent or not permanent. He's working through some things personally."
Moore was not at team meetings Friday morning. Pelini said he had conversations with both Moore and his father soon after.
The coach said he didn't want to get into specifics but is leaving the door open for Moore to return to the team.
Pelini said he talked again with the offensive lineman's father, former Husker tight end Brian Moore, on Saturday morning.
"He said there's a bunch of things being said out on the Internet ... the blogs and whatever ... that aren't true," Pelini said.
Pelini said Moore was "doing a good job" in fall camp before his departure.
"Obviously, like anybody else, he had some things to work on."
The 6-foot-6, 305-pound Moore was seen as one of the prized members of Nebraska's 2011 recruiting class. That class also included running back Aaron Green and offensive lineman Ryan Klachko, two touted recruits who have left the program since the end of spring ball.
Though Moore came from Clearwater, Fla., he has Husker bloodlines, with his father and cousin, Jay Moore, both playing for Nebraska.
And he made history last year when he became the first true freshman offensive lineman to start a season opener for Nebraska. He started the first four games at right tackle before veteran Marcel Jones took over most of the snaps during league play.
While Moore is just entering his sophomore campaign, he has already been through two springs in the Husker program and, according to coaches and players, is no longer viewed as a young player.
"He's much more of a veteran than you'd think a true sophomore would be," offensive line coach Barney Cotton said in the spring. "We don't consider him a young guy. He's a young guy age-wise but not experience-wise. He has a lot more experience than many guys that you're trying to plug in as a starter."
Because of that experience and high ceiling for potential, many considered Moore the front-runner heading into fall camp for the starting left tackle spot, though it appears Brent Qvale has been making a strong push there.
Pelini said Saturday Qvale's had "a heckuva camp."
As it currently stands without Moore, the leading candidates at the tackle spots are juniors Andrew Rodriguez, Jeremiah Sirles and Qvale. Pelini also mentioned redshirt freshman Givens Price as someone who is improving.
"I think he's a ways off, but he's shown me a lot over the last couple days," Pelini said of Price. "And I think (redshirt freshman) Zach Sterup is going to be a good player in time. ... You just look at him physically from when he came in and joined us to where he is now, it's night and day. So we have some good options at the tackle position."
