Let's just wait and see, looked a fairly innocuous challenge which obviously makes you worry more. Lejeune's done both knees, it's not the big deal it was 10-15 years ago in my opinion. He'll most likely miss the rest of the season and be ok for next, could also just be a twist in which case 3-4 weeks and he'll be right.
Trust me I'm a doctor!!
Its a bad one ... season over at least, so doubt we will pay anything in the summer
