1. 1-10 for A at its own 20 yard line. A1’s legal forward pass is caught by A2 at A’s 35 and runs to A’s 40 where he fumbles. A3 recovers the fumble at A’s 45 and runs to B’s 40, where he is downed. B1 was flagged for roughing the passer on the play.

2. A run by A1 leaves the ball close to the line to gain. Substitute A2 comes into the game, replacing A3 to be a 2nd tight end. After A3 reaches the sideline, the referee stops the clock and measures to see if there is a 1st down. After measurement the line to gain was reached so it is 1st down. Can A3 come back into the game for the upcoming 1st down play? If not, under what circumstances can he?

I have edited this to state how you need to state NCAA or NF, as in at least one of the plays, there is a difference in the rulings.

1. Unnecessary roughness on B, 15 yards from PBD. A1D/10 @ B-25.

2. Yes
