I don't think Bo wants to get a grass stain on his little red flag. I can't remember him ever throwing it.
No red flags in NCAA, only NFL. Also we had already used the one challenge on the Ball touchdown in the first half, so Bo was out. Supposedly, each play in a college football game is reviewed, but I'm not sure why they didn't review that one during a brief timeout. I thought in the stadium that it was incomplete. Watching a replay on TV last night, I thought it was probably a catch. QE caught it and reached out to try to get to the end zone, and the ball popped out when it hit the ground, although he was clearly down before.
"Once per game, each head coach may also call a timeout and challenge the ruling on the previous play before the next play starts. A coach must have at least one timeout remaining in order to challenge (teams receive three timeouts per half). If the challenge is successful and the on-field ruling is overturned, the team keeps its timeout and is allowed only one more challenge. If unsuccessful, the team loses its timeout and is allowed no more challenges."
