Reserve cornerback Mo Seisay, who didn’t dress for the opener, was back in practice Tuesday and performed well, according to defensive coordinator John Papuchis. Rex Burkhead stayed on the sideline.

Not too much of a surprise in regard to Burkhead, who’s questionable for Saturday’s game at UCLA with an MCL sprain. NU may not give a concrete status update on the senior I-back until just before kickoff.

Seisay, however, was healthy enough to participate Tuesday. “Looked good,” said Papuchis. The junior college transfer, who joined the program last spring, suffered an ankle sprain during preseason camp and it’s been bugging him ever since. It’s still unclear if he’ll be able to go Saturday.

More updates from Tuesday’s session are below…

>> Papuchis complimented the skill guys within the UCLA offense, saying they have enough athleticism to make some explosive plays against the Huskers. Properly defending the zone read option remains a focus. As does maintain discipline on the back-end — because Papuchis expects UCLA to test the NU safeties downfield.

>> There are some recruiting targets in California (uncommitted and committed prospects) that Papuchis hopes will take notice of Nebraska this weekend. Said Papuchis: “Getting out there and getting some exposure and hopefully playing really well will be good for us.”

>> The Huskers missed a few tackles in their opener. Is that concerning? “It’ll be more concerning this week if we see the same things,” Papuchis said. “I’ll reserve judgment on some of the missed tackle stuff until we evaluate us in this coming week.”

>> Sophomore Corey Cooper played well in his first significant game action as Nebraska’s No. 1 dime back Saturday, according to Papuchis.

>> Tight end Ben Cotton (ribs) was in full pads, but he wore a green no-contact jersey Tuesday. Bo Pelini said Monday that Cotton is expected to play.
