Possesion Arrow Error

[Jfpdi]

recently heard this happened at a local VB game. 3 mins left in game, V team scores and calls a timeout. Coming out of timeout H team is slow, V team player steps out of bounds for the throw-in. Offical gives player the ball and he throws it in and his teammate makes an uncontested 3. As soon as the V team completed the throw-in V coach is in officials ear telling him it is not correctable. After V team makes the 3, H coach realizes what happened and is somewhat upset. Other official T's him. H team lost by 5.
