I do. Houston scores on a long TD run when it is obvious runner is down. Jim Schwartz throws the challenge flag but is subsequently flagged for some dumb ass penalty and therefore challenge cannot be made.

Today, about a month later; Green Bay "fumbles" at the goal line and McCarthy throws the flag and NOW they can challenge the play because they know that they initiated the challenge before McCarthy throws the flag. NFL, where they make up rules as they go.
