"If he's got even a little niggle, then we won't be using him."
Barnes is more confident about the health of Canadian Test lock Tyler Ardron, who is bracketed with Michael Allardice.
Ardron suffered concussion against the Blues but has made good progress.
Co-captain Charlie Ngatai is back in the starting XV at fullback after Toni Pulu suffered a shoulder injury at training and will be out for at least two weeks.
Barnes acknowledged the Chiefs would face their greatest challenge of the season to date when they take on the Hurricanes.
"Right across the board they have an outstanding team, and they're playing some good rugby," Barnes said.
"If you have a look across the country you would have to say the Hurricanes are the team to beat, which provides us with a good challenge."
