The attacking talent was taken to hospital in an ambulance during Hinshelwood's teams 2-1 league defeat at Leatherhead.
Pattenden was given the 'all-clear' following a CT scan, sustaining 'whiplash' injuries.
Worthing hope the youngster, who was making just a second senior appearance, will not be out for too long.
But Hinshelwood says he will take the right precautions before considering Pattenden for a return.
He said: "We think it’s going to between two and three weeks.
“It’s one we’ve got to monitor carefully.
“It’s not like a kick to the calf, Jasper got a really nasty clash to the head so we’ll take the right precautions and make sure he’s fully up to speed before he’s back involved."
