Charlie Ngatai is set to make his second Super Rugby comeback of the season.
The Chiefs midfielder will return to his side's starting lineup for Friday night's clash with the Hurricanes in Wellington, having made a full recovery after a bout of headaches.
Ngatai missed an entire year of rugby after suffering persistent symptoms from a concussion suffered last year, before returning in some style to help the Chiefs beat the Reds a month ago.
But the one-test All Blacks was then laid low by headaches, causing him to miss his team's last three matches.
The 26-year-old will start at second five for Friday's potentially pivotal match, with the Chiefs and Hurricanes both fighting for second spot in the New Zealand conference.
