Rules Analysis
Traveling: The thrower must establish and continually maintain a pivot at the appropriate spot on the field until the throw is released. Failure to do so is a travel and is resolved according to 17.K.3, below.
If the travel occurs and no pass has been attempted:
The spot where the travel occured is the spot on the field where the thrower's pivot would have been had they not traveled. If the thrower threw from either the end zone or out of bounds, and their pivot was more than one step from the appropriate spot, the following procedure is used instead: First, the disc is checked in where the thrower threw the pass, making it live, then the thrower walks to the appropriate spot for their pivot and puts the disc in play. At this point, the stall count may resume.
Play does not stop. The defense (typically the marker) points to the spot where the travel occurred, and the thrower returns to that spot without delay. The thrower must touch the disc to the ground before attempting a legal pass.
The stall count is paused until the thrower sets a pivot where the travel occurred. The marker is not required to say "stalling" when resuming the count. The thrower must touch the disc to the ground before attempting a pass.
Play does not stop, but the disc is live, so it is still subject to a turnover (for example if the thrower drops it).
If the thrower wishes to contest the travel call, they announce "violation" and play stops. Upon checking the disc in, the stall count resumes at the count reached plus 1, or 6 if over 5 (15.A.5.a.3).
The marker must initiate a stall count with the word "stalling," but resuming the count does not require the marker to say "stalling" again.
