NEWS & NOTES

Mangum starts: After missing the past two games with an ankle injury, junior quarterback Tanner Mangum returned to the BYU starting lineup Friday against Boise State.

Mangum, a graduate of Eagle High, was injured near the end of BYU’s 19-13 loss to rival Utah on Sept. 9. The Cougars struggled in Mangum’s absence, losing to Wisconsin 40-6 and Utah State 40-24.

ESPN reported during the broadcast that Mangum was still walking in a boot on Thursday and his left ankle was heavily braced for Friday’s game.

Mangum told ESPN he was about “60 percent healthy, but mostly just sick and tired of being helpless” and wanted to go out there and do something about it.

BYU’s passing attack has struggled mightily, as the Cougars led the nation in interceptions thrown with 10 going into the game. Mangum was 49-of-90 passing for 466 yards with two touchdowns and four interceptions this season. He started two years ago in the Broncos’ last visit to Provo, and led the Cougars to a comeback win. He played sparingly in 2016 behind Taysom Hill, a Pocatello native.

Nawahine gets second career pick: When former Boise State coach Chris Petersen first offered Kekoa Nawahine a scholarship, Petersen wasn’t sure which side of the ball the Rocky Mountain High product would play.

Nawahine started on both sides of the ball in high school, and was an all-5A SIC first-team selection at wide receiver and safety as a senior.

The 6-foot-2, 199-pound Nawahine eventually settled at safety for the Broncos, but he flashed a bit of his receiving skills with his second career interception against BYU. Nawahine intercepted Mangum in the second quarter and returned it 51 yards. His pick led to a 20-yard field goal by Haden Hoggarth and a 10-7 Boise State lead with less than 2 minutes left before the half.

Quick hits: Boise State senior center Mason Hampton and junior tight end Chase Blakley did not play. Hampton was seen with a boot on his right foot. With Hampton out, sophomore Garrett Larson started in his place. Hampton had started the first four games of the season. … The Broncos used a fifth offensive line combination in as many games. … Redshirt freshman running back Robert Mahone carried the Hammer and junior defensive end Durrant Miles carried the “Bleed Blue” flag. … Redshirt freshman Avery Williams got his first start at cornerback for Boise State.
