That's why I got thrown out.... Our middie got hurt and went down clutching his ankle and howling in pain but the ref wouldn't stop play.... So I got three inches from his face and let him have it, it was only when hr blew the whistle to throw me out our team trainer could get on the field....
Yes, just like in football, even if a player other than the ball carrier goes down the play doesn't stop until the whistle is blown. In lacrosse its even more complex because an injury does not "normally" produce a whistle. Only penalties, goals or time outs. If the player is down in the middle of a scrum they will blow the play dead for safeties sake but if the player is down out of harms way the play continues.
I helped coach a U13 game tonight and our goalie went down with a hamstring and was laying in the crease, the coach noticed as the ball changed possession and was coming into our defensive half of the field. He couldn't call time out until we regained possession and then we could help the goalie out and swap goalies.
When the native indians played the game of "lacrosse" as the French settlers nick-named it( La=The-Crosse=Stick/lacrosse=the stick ), they played until only one man was left standing alive.
Lacrosse is the oldest team sport in North America!
