From what I remember, they didn't show the replay that best showed the ball hit the turf until after the next play. Also remember the broadcast delay - what is it, ten seconds?
Smart move by Green. Injured on the play and knowing he hadn't caught the ball cleanly, he staggered to his feet and stayed in the game to make sure there wasn't an injury timeout. That prevented the Ticat spotters from seeing the replay in time to throw the challenge. Good situational awareness on his part.
And HfxTC, it definitely wasn't a catch. And if the Command Centre had reviewed it and had not overturned it, Austin would have been calling for Jake Ireland to be fired immediately, if not sooner.
