Stumper (Weeks late but a day early)

[mikesears]

Just got back from a trip to Disney World with my family. I didn't touch a computer while I was there. GREAT FUN!
My trip to Disney caused me to postpone my question; thus, I am a week or two late. I am supposed to post on Saturday, but that day doesn't work well for me so I am posting a day early. Enough of my rambling excuses.....


1/10 from A's 20 yard line. A1 runs to A's 25 where he is tackled and injured. The clock (a) reads 30 seconds remaining in the 1st quarter (b) expires for the 1st quarter (c) expires for the first half. After the officials have stopped the clock for the injury, the coach requests a timeout. He then tries to send A1 back into the game. Ruling?
