Technical Foul?

[acgod24]

A1 jumps towards the basket and tries to dunk. B1 meets him at the rim and commits a foul...a hard foul but nothing that would be considered intentional or flagrant. A1 loses his balance and lands on the floor right on his back in serious pain. After about 5-10 seconds on the floor, A1 gets up and (a) heads back to the locker room. The locker room is opposite the table so the trainer is probably about 40-50 feet behind him. Or (b) heads back to the locker room and is followed by A2 apparently to see if he is OK. Would a technical foul be warranted to A1 or A2 for leaving the court for an unauthorized reason?
