I had a motorbike accident and twisted my leg the wrong way round, my leg flopped to the side when they lifted the bike off and we thought it was a dislocated hip, ambulance men knew straight away and told me it's a body reaction, it flops like that and comes back but takes months for the cartlidge and ligaments to go back into place, it's like stretching an elastic band. Took me 5 months, and it's never the same. It looks like that's what happened to gomez, it'll go back but it'll take months and you can't rush it. I've ran 19 marathons since, after being told I'd be lucky to walk again, so hopefully he'll make it back onto the pitch, it'll just take time. Good Luck.
