Adrian Martinez filed up the stairs past reporters with the rest of his teammates Tuesday morning after practice, wearing a T-shirt and shorts and a sleeve over his right knee instead of a uniform.
It's not surprising the Nebraska freshman quarterback was held out — or at least mostly out — for a second straight day this week, considering coach Scott Frost said Monday that a decision on Martinez's availability for Saturday's game against Troy could be pushed to gameday.
In the meantime, though, Frost said on Tuesday's Big Ten coaches teleconference that Martinez can still get himself ready in other ways.
"He’s in the meetings, he’s getting some reps mentally and also getting some not-full-speed reps on the field," Frost said. "We’ll figure it out as it goes along, but we’re doing our best to get every quarterback on our roster at least familiar enough with the game plan to be able to go out there and function and execute.
"We’ll do the best we can and we just have to keep evaluating it day by day."
Frost on CU/Pac-12 decision: Frost had no comment on Colorado’s decision to not suspend freshman linebacker Jacob Callier for his role in the play on which Martinez was hurt.
“At this point we’re focused on Troy,” Frost said. “I told our (athletic director) Bill Moos about it, and he said the right protocol was to send it to the two conferences, so that’s what we did. I’m not going to say anything else about it.”
Right response: Erik Chinander's feelings in the wake of Saturday's opener against Colorado were somewhat predictable.
"Not good," he said. "We lost."
But the Nebraska defensive coordinator was pleased with the manner in which the team responded to a 14-0 deficit in the first quarter.
"They were dialed in, they were focused, they were ready to play," he said. "I knew if we got out there, I didn't know exactly what was going to happen, but I knew it wasn't going to be a 'give up,' I knew it wasn't going to be a 'surrender.' I knew we were going to keep playing and things were going to get better."
Difficult decisions: Chinander on Monday handed out Blackshirts to seven players — linebackers Dedrick Young, Mohamed Barry, Tyrin Ferguson and Luke Gifford; linemen Mick Stoltenberg and Freedom Akinmoladun; and cornerback Dicaprio Bootle.
Leaving out players wasn't easy, Chinander said.
"You know, you come in to be the defensive coordinator at Nebraska, and all you think about is how awesome the Blackshirts are," he said. "But then it's time to really get to the nut-cuttin' a little bit. You've got to do it, and that's hard. Really hard.
"I had to talk to every kid who maybe didn't get one, that maybe you guys think deserved one, that maybe the fans think deserved one."
But fans and media aren't in practice every day, or in meetings.
"We had to explain to those kids why they didn't get one," Chinander said. "For some of them, it's, 'You played great in the game. Now you need to compete with yourself in practice.' Or maybe you didn't go to class, maybe you're late for meetings, maybe it's other behavioral issues.
"Some guys are on the very cusp, and they played in the game like they should have. But their habits leading up to that thing didn't warrant it, yet."
Clean-up crew: Among the areas Nebraska aims to clean up this week is special teams. Of Nebraska’s 11 penalty flags against Colorado, four came on special-team plays, including two holding calls and a flag for a block in the back.
“First and foremost, I’ve got to coach better,” said Jovan Dewitt, who coordinates special teams. “You got to do that. I have to assume responsibility for those things. The errors that you did see, some of them were technique errors, some of them were effort errors. I know Cam (Taylor) had a holding call on a punt return and he was being too aggressive if there’s ever such a way to do that.”
