Watch: BYU calls timeout with Tanner Mangum missing from field
Mangum ran back from the locker room to run one final play with two seconds left in the half after the timeout. The Cougars were leading the Bulldogs 24–3 when Mangum was in the locker room as opposed to the field, possibly thinking the clock had already run out.
Mangum has been playing in place of the injured Taysom Hill, who sustained a season-ending injury in BYU’s season-opener. In 11 games, Mangum has completed 62.5% of his passes for 2,442 yards, with 16 touchdowns and seven interceptions.
