The change in the NHL's icing rule to reduce the risk for potentially damaging collisions partly stems from an incident that nearly ended Fedun's career.

After going undrafted, the quick-skating defenseman spent four seasons at Princeton University. He had his best season as a senior with 22 points (10 goals, 12 assists) in 29 games in 2010-11. The Edmonton Oilers, his hometown team, signed him to a two-year contract March 8, 2011, and he was impressive during training camp before the 2011-12 season. But Fedun fractured his right leg during a preseason game when he was tripped by Eric Nystrom of the Minnesota Wild in a race for the puck to force icing. He missed all of 2011-12; the change to no-touch icing was made for the 2013-14 season.

By then Fedun was in his second season with Oklahoma City, Edmonton's American Hockey League affiliate. He scored a goal in his first NHL game, Nov. 5, 2013, and scored his second goal two days later. He played four games in 2013-14 before being sent back to Oklahoma City.

Fedun spent the next four seasons bouncing between the NHL and the AHL. He played with the San Jose Sharks organization in 2014-15 and the Vancouver Canucks in 2015-16 before signing with the Buffalo Sabres on July 1, 2016. He had seven assists in 27 games with the Sabres in 2016-17, but spent most of 2017-18 ping-ponging between the NHL and the AHL. He had one assist in seven games with the Sabres.
