Tippett's jaw sustained a hairline fracture after a ruck collision with Shane Mumford and Callan Ward early in their 36-point loss to GWS at ANZ Stadium.
The big ruckman played out the match but appeared to be in discomfort and had little impact after suffering the injury, with scans on Monday set to reveal what medical treatment will be required.
Rising Star winner Mills felt for his hamstring in the second quarter and played no further part in the match after coming from the ground.
It is believed to be a grade one strain that could see him return for a possible preliminary or grand final.
Toby Nankervis looms as the likely replacement for Tippett while Jeremy Laidler is the favourite to fill Mills' half-back role.
