[Bchill24]

I can't seem to find the rule or case play to the following question?

While the ball is at the disposal of A1 and prior to A1 attempting his/her free throw, B1 in a marked lane space steps into the lane and back. Team A then takes a time-out. Following the time-out, A1 misses the free throw. Official sounds the whistle and awards A1 a substitute free throw.

I know it is a lane violation on B1 but since the shooter didn't shoot the ball and requested a time-out does the violation still carry after the time-out?
