After juniors, he played for the Sioux Falls Stampede of the USHL, earning a Division Icollege hockey scholarship to UMass Lowell. Ruhwedel played at UMass Lowell from 2010 to 2013.

On the same day, he made his NHL debut for the Sabres in a game against the Philadelphia Flyers. On July 16, 2014 Ruhwedel signed a two-year contract to remain with the Sabres organization.
