Panthers bench QB Matt Moore
Moore was pulled after getting sacked and losing a fumble on the previous possession with the Buccaneers leading 20-7 on Sunday.
Moore, who started despite suffering a concussion in a Week 1 loss, completed just 6 of 16 passes for 125 yards, one touchdown and one interception.
Clausen starred at Notre Dame and was taken by the Panthers with the 48th overall pick after a surprising slide in the draft.
