Abh - Likely Sentence

[Tom1245]

I was assaulted in an unprovocated attack a month or so ago. I was sat on a sofa at my friends hoise and 3 males who I didn't know entered through the back door of the house. I was kicked in the head without warning then punched across the nose. My nose was broken and has had to be realigned, i had a black eye and a cut across the nose that needed to be glued. The lad who hit me has been charged with ABH.. does anyone know what will the likely sentence be?

I have had a look at the sentencing guidelines but im not sure what is classed as serious injury or higher or lower culpability!

Thanks if you can help!
