Ranked 48th amongst North American skaters in Central Scouting's final rankings, Davidson was selected by the Oilers in the sixth round (162nd overall) of the 2010 NHL Draft.
2010-11: Davidson made his pro hockey debut appearing in two games with the Oklahoma City Barons, including one AHL playoff contest, following his second season with the WHL's Regina Pats. Davidson had no points or penalty minutes and was an even plus/minus with three shots on goal in limited action with the Barons. One of two Regina players to skate in all 72 games, Davidson was the club's third leading scorer as a defenseman with 8 goals and 44 assists and was -5 with 71 PMs on a Pats team that had the WHL's third-worst record.
2011-12: Davidson attended his second Oilers camp and returned to Regina for his third season Skating for the Pats as a 20-year-old, he was the team's third-leading scorer with 13 goals and 36 assists in 69 games and was plus-26 with 83 penalty minutes.

In 11 games with Stockton he scored 7 goals, including two in his first game, and had 5 assists; finishing +7 with 4 penalty minutes.
A late bloomer in every sense, Davidson is a no-nonsense, all-around defenseman. He does not excel in any one area, nor does he have too many glaring weaknesses. He could stand to be better when it comes to some of the finer points of his skating, pivots in particular, and he seems to be very adept at making the first pass out of the zone, but on the whole he is the kind of calm, unremarkable player coaches love to count on.
After being diagnosed with testicular cancer on November 1, 2012 and undergoing chemotherapy, Davidson made a much-anticipated return to professional hockey with the ECHL’s Stockton Thunder in the second half of the 2012-13 season. He seemed like he had never missed a beat, logging 12 points in 11 games and showing that he has some offense and can play some good hockey, health considerations aside. He will likely continue to split time between the AHL and ECHL in 2013-14, providing that he stays healthy.
