Wood, whose 24 league goals have helped propel Leeds firmly into promotion contention this season, sustained a knock during his country’s World Cup qualifying win against Fiji on Saturday.
The problem ruled him out of New Zealand’s return game with Fiji – which they won 2-0 in his absence overnight – and the 25-year-old is flying back to England to be assessed by Leeds ahead of their important trip to play-off rivals Reading at the weekend.
New Zealand coach Anthony Hudson does not appear to think the injury is significant.
“It’s not too serious but I’ve decided to be extra cautious. Chris is obviously a significant player and leader for us so it is a blow, but it’s important that we have a fit and healthy Chris Wood for the FIFA Confederations Cup and qualifiers late in the year,” he told nzfootball.co.nz.
Leeds will be hoping that defender Pontus Jansson (Sweden), winger Stuart Dallas (Northern Ireland), midfielder Eunan O’Kane (Republic of Ireland) and on-loan Swansea winger Mo Barrow (Gambia) return unscathed from their international exploits.
