Former All Black Adam Thomson joins the Chiefs two years after serious spine injury

The 37-year-old, a member of New Zealand's Rugby World Cup-winning squad in 2011, has this week joined the Chiefs as a replacement player.

The former Highlanders, Reds and Rebels loose forward played for Otago in last season's Mitre 10 Cup after a four-year stint in Japan with the Canon Eagles.

A Chiefs spokesperson told Stuff he was only signed on as All Blacks cover until early February at this stage, but said it was "highly likely" he would play in Friday's pre-season match against the Blues in Waihi. 

Chiefs hooker Liam Polwart retires aged 24 from rugby due to concussion issues

Polwart, 24, announced this morning he woun't take part in next year's Super Rugby season after deciding it wasn't worth the risk.

“It has been a difficult decision to make to leave the game I love," Polwart said.

"It has provided me with plenty of great friendships and some awesome experiences. I have had some on-going issues with concussion, and while I am currently symptom free, I chosen to hang up my boots and not to put myself at further risk.

"I don't see that as a forseeable option. He's contracted [to Montpellier], so we'll look at what we've got in our own group, in our region, and around the country," the Chiefs coach said on Tuesday.

Damian McKenzie (knee) and Tiaan Falcon (Achilles) are gone for the season, and Jack Debreczeni is a likely absentee for the coming weeks after suffering his second concussion in a month in last Friday's 23-17 loss to the Lions, leaving the Chiefs seriously short of playmakers ahead of facing the Hurricanes in Wellington on Saturday.
