loose ball in backcourt

[rsl]

Last night...

Partner is three seconds into a ten second count when ball is knocked away by the defense on full court press. Partner drops his count. The ball bounces around in the back court for a good five seconds when it is finally picked up again by the same team deep in their own backcourt. Three seconds later, the dribbler is double teamed and stopped, still in his backcourt.

As new lead (two man) I am helping cover the press from about half court.

Do I call the ten second violation, even though there is no visible count?
