"No one feels worse about this than Ed, but like the coaches and players in our high-speed game, mistakes will occur," NFLRA executive director Tim Millis said in a statement.
"The NFLRA stands by Ed Hochuli as a 19-year veteran with multiple Super Bowl and countless playoff game experience who has the integrity and character to admit a mistake and accept the criticism that comes with it."
Hochuli, a former NFLRA president, ruled it an incomplete pass. Replay ruled it a fumble, but it was spotted at the 10, where the ball hit the ground, and given to Denver because the rules did not permit possession to be awarded to San Diego because the whistle had blown.
Denver went on to score a touchdown and a 2-point conversion to win 39-38.
