I've been doing jiujitsu for 2 weeks now. Today I sparred with a blue belt. He submitted me with a leg triangle and I tapped almost instantly, but he hurt my neck in the process. Now, I can't say for sure if he was going too hard or he's just strong; but are injuries like this common? My neck pain is very bad right now, I'm having second thoughts on trying this sport.

I have experience in muay thai too. Muay thai spars are meant to be sabai sabai; fun, light, and playful. Never had I gone through any significant injuries in months of muay thai spars. Now I try jiujitsu and I have neck injury in the first 3 weeks. Is this common? If not, should I avoid the person?
