Rapid Reaction: Quarterback day at Husker spring practice

Nebraska quarterbacks coach Mario Verduzco works with quarterback Tristan Gebbia during spring football practice on Tuesday morning, April 3, 2018 at the Hawks Championship Center.

Here’s a quick rundown of the highlights from head coach Scott Frost and Nebraska’s quarterbacks.

* Four signal-callers met with reporters, while redshirt sophomore Patrick O’Brien declined to take questions.

* Frost said that Martinez told him that he thought his arm was at about 90 percent. Frost said he’s seen some times where perhaps Martinez didn’t have the “steam” on some throws that he saw on Martinez’ high school tape.
