Papac and Weiss come in for Rangers
Inverness youngster Nick Ross has been dropped to the bench in favour of attacker Eric Odhiambo for the visit of Clydesdale Bank Premier League leaders Rangers.
The teenager, who has been a regular for Caley Thistle this season, is understood to have an illness and is replaced by Odhiambo who netted the late leveller in the 1-1 draw at Ibrox in October.
