While the two-test All Black will be missed, a former All Black in Brendan Leonard is ready, having nearly fully recovered from his own broken cheekbone.
Leonard has been coming back to match fitness via the Chiefs development team, and will be in line for selection against the Blues.
Chiefs coach Dave Rennie confirmed the worst after Kerr-Barlow was treated on the weekend.
"(His) face was swollen after the game," Rennie said.
"He had a scan the day before and there was nothing visible other than something around his wisdom tooth (which Kerr-Barlow had mentioned earlier)."
Rennie said to the Waikato Times it was good to have Leonard back.
"It's good timing with Harry coming back in but it's tough for Tawera and he's pretty gutted," Rennie said.
