Intentional Foul

[RookieDude]

H.S. Boys Varsity Jamboree the other night.
A smaller 3A school is beating a larger 4A school by 18 pts. halfway through the second half. (two 10 minute halves)
After a throw-in, a frustrated 4A player was running along side a 3A player and decided to foul his opponent hard.
The 4A player took a step toward the 3A player and using his hip...knocked the 3A player two or three steps sideways.
The ball was nowhere near the two players.
The foul didn't look hard enough to be flagrant...but, a common foul didn't seem like enough "punishment". Neither team was in the bonus.
There was definetly "intent" by the 4A player to foul the 3A player.

What's your call?
I will post what was called after I get a few responses.

Thanks,
Dude
P.S. I will say that the Coach didn't say anything to the calling official...but told the non-calling official that it "should have been a double foul".
