losing control of throw in

[thedewed]

this happened in d2 college game and someone asked me about it. throw in along sideline, ball handed to player, he winds up to throw it, loses control and it goes behind him into the stands.

the official gets it back from the fan and gives it back to player, resetting and allowing throw in.

no reason this should have been allowed, right? actually was end of game situation, team with ball had one point lead, ended up winning. i say if ball given cleanly to throw in and he loses it, it's a violation.
