I was watching the replay of the Georgia/Georgia Tech game from a few weeks ago, and this situation came up and my gut told me this didn't sound right, so I figured I'd ask the experts.
The score is tied 14-14, UGA ball, 1st and 10 at UGA 9 yard line, :56 remaining in the second quarter. UGA hands off up the middle for a gain of 4 yards, and a GT player is injured, for which the officials stopped the clock and announced an injury timeout with :45 remaining on the game clock.
R announces that Georgia has elected not to use a timeout, therefore 10 second runoff applies.
3-3-5 F-4 states, "There is no option for a 10-second runoff if there are injuries to opposing players." Does this mean in this case there should not have been any option for a runoff, or is it possible that UGA had the option, but should not have had to burn a timeout if they wished to preserve the 10 seconds?
