Ryan Keiser was a four-year player and a former walk-on who started in parts of his junior and senior seasons at safety. He was an example of steadiness for most of his career, playing on special teams both in coverage and as the holder for the field goal kicker across his four seasons. Keiser finished his Penn State career with 78 tackles and 4 interceptions.
Keiser's redshirt senior season of 2014 was cut short by a serious injury just days before Penn State's double-overtime loss to Ohio State. A broken rib caused more significant damage to his bowel and left him in intensive care for a time.
