DT McDonald, DE Ayers, RB Martin out for Bucs on Sunday
The Bucs will face the 49ers on Sunday without starting DT Clinton McDonald, who was ruled out Friday after returning to practice for two days in a limited capacity as he recovers from a hamstring injury.
Also ruled out were RB Doug Martin (hamstring) and DE Robert Ayers (ankle), who will both miss their fourth straight game due to injuries suffered in Week 2. Neither has practiced all week. McDonald misses his second straight game, which pushes backup Akeem Spence into a starting role as he had in last week's win against Carolina.
The Bucs listed five players as questionable, but all have had consistent participation in practice and should be able to play Sunday: DT Gerald McCoy (calf), TE Luke Stocker (ankle), WR Cecil Shorts (ankle), C Joe Hawley (knee) and CB Jude Adjei-Barimah (knee).
As expected, the 49ers will be without their top running back, Carlos Hyde, who was ruled out Friday with a shoulder injury suffered Friday. Their backups have had only limited playing time this season, a major advantage for the Bucs.
