My sister wants to play football? Thoughts?

So, my 13 year old sister, 14 in a few months, wants to play football. She's about 5'2, weighs 117 possibly. She's got an amazing throw, kick, and makes great catches. I'm a football player myself. I've played quarterback for 6 years. She's good as some of the guys on my school's Junior High foot ball team. She can kick about 30 to 20 yards, and may I mention she runs well also. Very good at tackling too. I want to make her dream come true, but the fact that she has never in her life broken a bone, and has panic attacks, what should I do, and what position would she be best in? There is no law in letting girls play football, also. I think she's best at kicking, catching and running.
