I try not to be a pessimist, but I am a realist and the concern for me is that Martinez confirmed it was a medial knee ligament tear.
I sustained that injury playing a match when I dislocated my patella. There are different grades of MCL tears, 1 to 3 with 3 a complete rupture which is what I had. From what we have heard already about the amount of swelling it is at least a grade 2, which is 3-4 weeks minimum rest before beginning rehab. I was immobilised in a knee brace for over 6 weeks and, although it is 'unlocked' a bit at a time to allow you to gently begin to manoeuvre it, when it was taken off I could barely bend my knee at all - some others on here will probably have experienced this, for a while you wonder if you will ever be able to fully bend it again! They don't usually choose to operate on an MCL like an ACL, which is a benefit, as less chance of any other problems like infections getting in a wound.
Considering I am in my mid-30's and only reasonably fit compared to an athlete like Ross and had to go to work rather than being able to spend all day doing physio, let's hope these kind of recovery times are reduced.
Here's hoping it is only a grade 2 and it is closer to the 7 weeks for the lad. It is sad for us, but must be devastating for him at such a key moment of his career, coming off the back of the World Cup.
