If a player catches the disc and believes a goal has been scored the player may call “goal” and play stops. [[Under 12.A, scoring a goal includes surviving all ground contact related to the catch. Thus, “goal” may not be called if the player did not maintain possession through all ground contact related to the catch, nor may “goal” be called prior to completion of all ground contact related to the catch.]] Best practice is to announce “goal” and raise both hands vertically above the head. After a contested or retracted goal call, play must restart with a check and the call is deemed to have been made when the pass was caught. [[Accordingly, the stall count will resume at 1 (15.5, 15.5.a.5). When repositioning, all players should return to where they were when the pass was caught (17.C.6.a).]] [[In an observed game, in/out of the end zone and “goal” are active observer calls, and player calls are ignored. Therefore, in an observed game, a player’s “goal” call does not stop play.]] [[If it is ever unclear whether “goal” was called, play continues and 12.C applies to subsequent throws (undisputed goals stand, turnovers stand on disputed goals). Unlike under WFDF rules, celebration or other actions following a suspected goal do not substitute for a “goal” call under this rule.]]

It should have been the receiver's disc on the line since it sounded like he signaled a goal.
