<human>: This actually happened on Saturday. After a long week of tests and presentations for College, my friends and I thought it would be a good idea to have our girls over and just get sloppy drunk.

To preface this, I took Mixed Martial Arts for 4 years and have won quite a few local and state tournaments. My best friend (we'll call him Ryan) recently expressed interest in learning to fight, so I've been teaching him some stuff in our campus' boxing gym.

We were 2 bottles of fireball in (split between 4 people) and we're standing in the hallway in front of our suite. Ryan was on the phone with his girlfriend back home, and I thought it would be funny to roundhouse him in his hip. I only tapped him, because my only intention was to scare him. 

He saw my leg coming and freaked out. He dropped and broke his BRAND NEW iPhone 6S, went to move and rolled on his ankle. We brought him to the hospital and he fractured his ankle and tore his ACL.

Ryan's a 3 time D2 National track and field champion; specifically in sprinting and pole-vault. The doctor said it's going to be very difficult for him to re-train himself after being in a cast for a long time.

Can you condense the text into a few key points?
<bot>: Roundhoused my friend in the hip, he fell and fucked up his ankle. No more pole-vaulting for him
