Car Accident Help In California?

Today, I was involved in a car accident. I was going through an intersection (going straight). My light had turned yellow and a car turning left hit me on the front driver side fender. He is now claiming that he has neck issues and was taken to the hospital (after he cussed me out even though he hit me). I have a witness who saw him hit me, but it will take 7-10 days for the official police report. I just want to know what may happen in the police report. He had 2 other adults in the car who are "backing him up" where I only had my 4 year old daughter (who is fine). His car is way more damaged than mine (hood folded up pretty good) where as he hit my front right wheel causing the bumper to come off and the anti freeze compartment to be damaged and cause leakage. I'm just wondering what may happen??? It's hard waiting for the official report because you don't know what the other people are saying....
