Mayfield didn't practice Wednesday due to a knee injury.
In addition to Mayfield, three key skill-position players for the Buccaneers -- wideout Mike Evans (rest), tight end Cade Otton (knee) and wideout Sterling Shepard (foot) -- sat out the first practice of Week 16 prep, while running back Bucky Irving (back/hip) was a limited participant. As a result, the group will be monitored as the week goes on to see who will be available for Mayfield in the event the quarterback also is cleared to play Sunday at Dallas.
