Here are some quick notes and observations to pass along from Nebraska's half-pads practice on Monday afternoon inside the Hawks Championship Center and fields north of Memorial Stadium...

***Quarterback Tommy Armstrong did not practice and had a boot on his right foot. Armstrong was wearing a boot after Saturday's game as well. Head coach Mike Riley was not available to comment following practice.

***Linebackers coach Trent Bray confirmed that linebacker Michael Rose-Ivey would be available for Saturday's game against South Alabama and was not the one suspended player.

***In an effort to bolster the front four pass rush, defensive coordinator Mark Banker didn't rule out the possibility of Rose-Ivey lining up at defensive end in obvious passing situations. Banker said they worked on that a bit in the spring but have not done it yet this fall.

***Banker said there was "no hangover" for the team as it returned to practice for the first time after the Hail Mary loss to BYU. He said NU "backed off physically" a bit to let guys heal up, but still got in a lot of reps and the defense got going with first and second down work for South Alabama's offense.

***Banker said the team watched film of the BYU game on Sunday and then again prior to Monday's practice. The Huskers' defense then picked out about 14 bad plays from that game - including the Hail Mary - and worked on them again, since staff knows other teams are going to see those mistakes on film and try to exploit them as well.

***Banker said he wouldn't change Nebraska's defensive call on the Hail Mary after looking at it again on film. He said BYU had seven blockers in pass protection and only three receivers, so NU liked the odds of preventing a completion - which obviously it did not do.

***Banker said young defenders Aaron Williams Dedrick Young and Luke Gifford were all "in the eye of the storm" on Saturday and made both good plays and bad plays, including some "critical errors." Banker said Young played "a whale of a ball game" but had at least one big mistake, and that Gifford and Williams held their own but definitely weren't perfect.
