Collision with the Coach

[RANCHMAN]

I was hoping to get some advise on how you would handle this situation.

Team A has rebounded a missed shot by team B. Team A moves quickly toward the front court, and I am the new trail (two man mechanics), running along the table side. I am looking over my shoulder when I crash into the coach. She is at least two steps on the court when this occurs, and I fall down, but I am not injured, so what violation do I have here in your opinion? I issued a Technical foul for standing on the court. I thought a Flagrant Technical would be too harsh because it was early in the first quarter, so she had not been observed standing in the playing area.
Do you think I made the correct call?

Thank you for your help!
