Adam Thomson's immediate playing future with Otago, the All Blacks and the Commonwealth Games sevens rugby team is in limbo after he injured a knee during a national provincial championship match yesterday.
Quality loose forward Thomson suffered medial ligament damage late in the 13-8 loss to Northland in Dunedin - his 50th match for Otago.
The 28-year-old was to be assessed today once swelling had subsided.
Thomson has been a standout figure for a struggling Otago side, putting himself firmly in contention for the All Blacks' season-ending tour.
Before that side is named, Thomson is due to be part of New Zealand's sevens campaign at the Commonwealth Games starting in New Delhi in two weeks.
Also in doubt for the Games are sevens captain DJ Forbes, who has barely run for the past two months while recovering from a groin injury and playmaker Tomasi Cama, who fractured his cheek last month playing for Manawatu.
Forbes returned to the fray off the reserve bench for Counties Manukau in yesterday's loss to Bay of Plenty.
