Wanted to call something

[MOFFICIAL]

I was officiating a men's league game at the YMCA. A shot was taken it was missed and rebounded. Heading up court. My partner and I blow our whistles at approximately the same time. His for an injured player and mine for a pretty serious bump on the dribbler. We confer and he said he blew first-but I really wanted to call my bump also because it was pretty hard and maybe deliberate (but how do you judge intent).
Is there something I could have called to send a message on the rough play?
