make the call

[tball]

I've been reading these bb and fb forums for 2 years and now i have a situation that I'd like to share. This situation occurred in a varsity HS game last friday. Looking for comments on how to handle-

1st and goal-A ball on B 9 yard line. Team A throws quick out to receiver A2. A2 catches ball w/ knees on goal line inbounds, ball does not cross the plane of goal line. Player A2 then fall out of bounds after catch.

Team A did not call time out, no official killed the clock. The timeskeeper, thinking the ball was in the end zone or out of bounds, stopped the clock w/ two seconds.

How would you proceed?
