Rule 4 Section 5 Article 1
Item 3: Consecutive Team Timeouts. Each team may be granted a charged team timeout during the same dead-ball period, but a second charged team timeout by either team during the same dead-ball period is prohibited. Such team timeouts may follow a Referee's timeout or any automatic timeouts in Section 4 above.
The rule does not apply to just kicking situations. There is an unsportsmanlike penalty if this is tried though to "ice the kicker."
Item 4: Unsportsmanlike Conduct. An attempt to call an excess team timeout or to call a second timeout in the same dead-ball period by Team B in an attempt to "freeze" a kicker, will be considered unsportsmanlike conduct and will subject the offending team to a 15-yard penalty (See 12-3). This will apply to field goals or Try attempts.
Note: If an attempt is made to call a timeout in such a situation, the officials shall not grant a timeout; instead, play will continue, and a penalty will be called, with customary enforcement. If a timeout is inadvertently granted, the penalty shall also be enforced. See 12-3-1-v.
