Very sad news but not unexpected given the circumstances of his injuries.

Just hope he can get back on the field for the rest of this year before he hangs up his boots.

Fine player such a sad end to what should have been a glittering career

Absolutely gutting for the player, club and fans. Everyone single person wanted this guy to get fully fit.

He's worked so hard and always given everything. Good luck Dom, in whatever you do next. Short term, let's hope he gets fit and gets back on the field and plays some good rugby.

Cap space and money well spent waiting to see if he could regain full fitness, Five years well spent Mr IL

Get a grip.

Best wishes to Dom - must have been a tough decision to make.

Absolute weapon.

Well his two tries effectively prevented Wire winning the GF giving us another Championship and preventing them from winning once since 1955 so money well spent.

Don’t feed the troll.

Expected him to leave but didn’t expect him to retire. Great shame as he was super talented, just serious injuries got the better of him. I wish him well in whatever he chooses to do next

Such a shame but he's got to put his long term health first

Hard as nails and one of the best!

Hope he can get back to full fitness soon.

The truth hurts and I'm the only one willing to say it as usual, Uncle Mo and DW wouldn't have gone the same route

Oh and btw

Have I stated he was crap or rubbish

I think not

Look up 'tactful'.
