from Kerry Fraser of TSN,

I give young referee Francis Charron kudos for having the courage to correctly apply rule 69.3 and disallow the potential go-ahead goal by Ryan Callahan with 4:22 remaining in the second period and the score tied 1-1.

The overriding rational of rule 69 (Interference on the Goalkeeper) is that a goalkeeper should have the ability to move freely within his goal crease without being hindered by the actions of an attacking player. There were two instances of goalkeeper interference by virtue of the rule on the play whereby a goal could not legally be allowed to stand if the puck entered the net.
