Yes.
Simply put... Yes.
Stopping the game because a player is hurt.
According to the NFL rulebook, the first injury results in a fourth timeout being charged to the team with the injured player. What that means, in effect, is that the opposing team has one of its timeouts restored. So if neither team had any timeouts left, the team with the injury is basically given a pass the first time it happens, but the opposing team now has one timeout left.Any additional injury timeouts result in a 5-yard penalty for delay of game, if the clock was running. If the clock was running and the score is tied or the team with the injury is behind, a 10-second runoff is also imposed.
Any player on the field of play or the head coach of the team may call a timeout.
I think you can do it as long as you are playing a game.
No, the coach would sub in another by way of calling a timeout. I would, anyway
Yes. Instead of taking an injury timeout which would have forced Woodson to leave the game for at least one play, the Packers used one of their timeouts which allowed him to be in the game for the next play. He left the game for good after that play.
Yes. It isn't football where the player can simply go to the sidelines and get checked on. They take him/her to the locker room and they can return at anytime.
You can call a timeout whenever you would like to.
No, the player can continue on playing. But if the injury was serious enough for play to stop, they usually will go to the bench, if only for a moment, before returning.
NFL injury reports are given on a game by game basis. If a player is listed as 'out', they are out for the team's upcoming game. A new injury report will be created for the next game and possibly that player's status will change and they will be able to play.
Typically 1 30sec timeout is allotted per game
If the player gets thrown out of the game they can't come back in. If it is an injury, I have no clue.
