travel then hard foul

[oc]

A1 goes in for a lay-up and travels (3 steps) followed by B1 fouling A1 hard nocking A1 into the second row. Hard enough to be an intentional foul-probably not flarant.

What's the call-HS Fed rules? I'm thinking just a travel but the foul was pretty hard to ignore. Can it be a technical on a dead ball even though it happened so fast the travel wasn't called yet?

Saw this in the Rockets-Suns game. Of course since this is NBA so the travel wasn't called. A1 saw the foul coming and braced for it-maybe even went looking for it. Refs called normal foul.
