Palmer caught his only target for an eight-yard gain in the Buccaneers' 25-11 loss to the Eagles on Monday night.
The speedy rookie logged a solid 34 snaps, but Baker Mayfield looked the way of Deven Thompkins four times to Palmer's one. The week-to-week production of both depth wideouts will remain difficult to trust as long as Mike Evans and Chris Godwin are healthy in front of them.
