Yeah, it's always happened and been part of the game but it just seems to happen more often. I can't recall, is there a penalty after a certain amount of times? I know the player has to sit out a down but does time come off the clock and after X amount of times does a team get penalized with yards?

INJURY TIMEOUTS
Article 2 If an official determines a player to be injured, or if attendants from the bench come on the field to assist an injured player, an injury timeout will be called by the Referee.
A.R. 4.7
Runner A1 is tackled and appears injured since he does not move.
Ruling: Official should call timeout for injured player. Official should not try to determine if player is injured.
Timeout is not charged if conditions are not violated.
INJURY TIMEOUTS PRIOR TO TWO-MINUTE WARNING OF EITHER HALF
Article 3 When an injury timeout is called, the injured player must leave the game for the completion of one
down. The player will be permitted to remain in the game if:
(a) either team calls a charged team timeout;
(b) the injury is the result of a foul by an opponent; or
(c) the period ends or the two-minute warning occurs before the next snap.
At the conclusion of an injury timeout, the game clock will start as if the injury timeout had not occurred. If either
team takes, or is charged with, a timeout, the clock will start on the snap.
INJURY TIMEOUTS AFTER TWO-MINUTE WARNING OF EITHER HALF
Article 4 After the two-minute warning of a half, the following shall apply:
(a) If a team has not used its three charged team timeouts, the team of the injured player will be charged
a team timeout, unless:
(i) the injury is the result of a foul by an opponent;
(ii) the injury occurs during a down in which there is a change of possession, a successful field goal,
or an attempted Try; or
(iii) the opponent calls a timeout.
(b) If a team has used its three charged team timeouts, an excess team timeout shall be called by the
Referee, unless:
(i) the injury is the result of a foul by an opponent;
(ii) the injury occurs during a down in which there is a change of possession, a successful field goal,
or an attempted Try; or
(iii) the opponent calls a timeout.
Penalty: For the second and each subsequent excess team timeout after the two-minute warning:
Loss of five yards from the succeeding spot for delay of the game.
(c) The player must leave the game for the completion of one down, unless:
(i) the injury is the result of a foul by an opponent; or
(ii) either team calls a charged team timeout.
(d) No yardage penalty will be assessed for the first excess team timeout, but a 10-second runoff of the
game clock may be applicable pursuant to (f) below. At the conclusion of an excess timeout taken
while time is in, the game clock shall start with the ready-for-play signal. For any excess timeout
charged to the defense, the play clock is reset to 40 seconds.
(e) If the Referee has already called an excess team timeout in that half for a team, any subsequent
excess timeout for that team will result in a five-yard penalty. (Such penalty shall be considered a foul
between downs and will not offset a foul by the defense or be part of a multiple foul by the offense.)
(f) If an excess team timeout is charged against a team in possession of the ball, and time is in when the
excess timeout is called, the ball shall not be put in play until the time on the game clock has been
reduced by 10 seconds, if the defense so chooses.
A.R. 4.8 Offensive team A, in the last two minutes of the half and the clock running:
a) Requests its fourth timeout because of an injured player.
Ruling: Granted. No five-yard penalty. Player has to be removed. Ten-second runoff. Ball will not be put in
play until the Referee blows his whistle and gives the wind-the-clock signal.
b) Requests its fifth timeout because of an injured player.
Ruling: Granted. Five-yard penalty. Player has to be removed. Ten-second runoff. Ball will not be put in play
until the Referee blows his whistle and gives the wind-the-clock signal.
SUPPLEMENTAL NOTES:
(1) Either half can end as the result of the 10-second runoff referenced in (f) above.
(2) If an injury timeout is called for both teams during or after a down, charged team timeouts and/or
excess team timeouts are charged as appropriate, but no yardage or 10-second runoff penalties shall
be enforced.
(3) If a foul by either team occurs during a down in which there is also an injury, such foul does not affect
the charging of an excess timeout, but it does prevent a 10-second runoff that may result from the
excess timeout, because the foul stopped the clock.
(4) The Competition Committee deprecates feigning injuries, with subsequent withdrawal, to obtain a
timeout without penalty. Coaches are urged to cooperate in discouraging this practice.
(5) There can never be a 10-second runoff against the defensive team.
