To be fair it's not news, possible ACL but it may not be and if it is we don't know what grade and anyway we won't know until sometime in the week when he can go for a scan.
It's ITK gold, you can not be wrong.
This, they'll suspect something but there's a lot of difference between a grade 1 and a grade 3.
People need to wait until the swelling goes down and he has the scan.
