Sam McKewon and Jon Nyatawa break down the key plays in the Nebraska-SDSU game, one quarter at a time.
* * *
Ameer Abdullah: On Nebraska's first play from scrimmage, the I-back rips off 24 yards on a cutback run.
Tommy Armstrong: Starts at quarterback and completes his first career pass, a 28-yarder to Abdullah, who's running a wheel route out of NU's inverted wishbone formation.
Armstrong: Executes a speed option perfectly, freezing a defender with a quick duck into the line before pitching to Imani Cross for a 5-yard touchdown. NU leads 7-0.
Cam Jones: The big SDSU tight end catches passes of 15 and 16 yards to start the Jackrabbits' first drive.
Zach Zenner: The FCS All-America running back doesn't disappoint, bolting 40 yards for a TD to tie the game. NU linebacker Josh Banderas vacates the middle of the field to cover Jones.
Quincy Enunwa: On third-and-12, the Husker senior makes a 33-yard catch down the sideline, dragging a foot as he falls out of bounds.
Cross: Finishes NU's second drive with a 2-yard, hard-driving touchdown. NU takes a 14-7 lead.
Zenner: On third-and-2, he patiently works around the right side of his offensive line before hitting the jets for a 35-yard run. NU, again, misjudges his speed. He later finishes the drive with a 3-yard TD to tie the game at 14.
Abdullah: Loses his second fumble in as many games, getting the wind knocked out of him as he does. SDSU recovers.
Zenner: Goes over 100 yards for the quarter as SDSU moves inside the Husker 5. The Jackrabbits appear to score a go-ahead TD, but are called for offensive pass interference.
David Santos: The sophomore linebacker sacks SDSU quarterback Austin Sumner for an 8-yard loss. One play later, Sumner is sacked by Avery Moss and Randy Gregory, forcing a 48-yard field goal from Justin Syrovatka. SDSU leads 17-14.
Winston Wright: The SDSU corner is dubiously flagged for pass interference on Enunwa.
Ron Kellogg: NU's other backup makes his best play, stepping up in the pocket for a 17-yard pass to Jake Long.
Abdullah: Atones for the fumble with a solid drive, including runs of 7 and 14 followed by a 1-yard TD plunge.
John Stiegelmeier: On fourth-and-2, SDSU's head coach elects to punt from midfield. Nebraska has not come close to slowing the Jacks.
Enunwa: On Nebraska's ensuing series, he catches a 12-yard pass from Armstrong on third-and-10 to keep the drive alive.
Armstrong: Runs for 12 yards on a zone read, then throws a 16-yard touchdown to Sam Burtch, who's running a post-corner route. Nebraska leads 28-17.
Stanley Jean-Baptiste: Steps in front of a poorly judged Sumner pass for his fourth interception of the year.
Kellogg: Zips a 23-yard touchdown to Tyler Wullenwaber. It's Kellogg's best pass of the first half.
Stiegelmeier: After punting on fourth-and-2, he goes for a fourth-and-14 from the NU 29, coming up a yard short. It's the second “blink” of the half from the SDSU coach.
Kellogg: Runs the two-minute drill with sharpness, completing four straight passes to move NU inside the SDSU 10. But the drive stalls there, and Mauro Bondi kicks a 22-yard field goal to end the half. Nebraska leads 38-17.
Abdullah: After Nebraska forces a punt, he runs for 41 yards on NU's first offensive play.
Kenny Bell: He'd dropped a TD in the first half, and now he fumbles after catching an Armstrong pass. SDSU recovers at its own 10.
Zenner: Runs for 16 yards off tackle, reaching the 200-yard plateau on just 20 carries. But he drops a swing pass later in the drive, a costly mistake that helps kill the Jackrabbits' drive. Syrovatka misses a 33-yarder, and SDSU's hopes appear dashed.
Armstrong: Fumbles on Nebraska's ensuing drive, but receiver Jordan Westerkamp bails him out by recovering it. Armstrong then completes three passes to help NU reach the SDSU 10.
Terrell Newby: Squirts through a hole, then crawls to the end zone for a 10-yard score. NU leads 45-17.
Randy Gregory: Like a big puma, he steps in front of another poorly judged Sumner pass and returns it 33 yards for a touchdown. It's the Huskers' third pick-six of the year.
Cam Jones: SDSU's tight end leaks out into the flat. He's wide open. Eventually, NU's defense brings down the 250-pounder, but after 25 yards.
Zaire Anderson: NU blitzes and Anderson comes free, dropping Sumner for a 7-yard loss.
Alonzo Moore: He catches a quick screen pass and accelerates into the open field. He gains 19 yards on the play — and a 15-yard late hit penalty puts NU in scoring position.
Newby: He gets his second TD of the game, scoring from 5 yards out.
Aaron Curry: Sumner tries to elude the rush, but Curry tracks him down for an 11-yard sack.
Charles Jackson: He gets credited with the forced fumble as running back Isaac Rodriguez powers into the second level. Jonathan Rose recovers the loose ball.
