Throwing program for 17yr old

My son was just released from where he had labrum surgery at the end of march.He has followed the pitching program givin to him by his surgeon.He will be done with it in about 2 weeks.The program has him long tossing and will be back throwing at 100% with curve and change ups.where do we go from here?How many times a week should he throw and pitch count.The rest of the team are just conditioning but he needs to throw to get his strength completely back.any throwing program would be greatly appreciated.thanks
