Spikes' absence not injury-related

FOXBOROUGH, Mass. -- Patriots offensive tackle Marcus Cannon (ankle) and wide receiver Aaron Dobson (foot), who both missed Week 13 against Houston, sat out Wednesday's practice session. Linebacker Brandon Spikes also was not present, but his absence was not injury-related.

Four cornerbacks -- Aqib Talib (hip), Alfonzo Dennard (knee), Kyle Arrington (groin) and Marquice Cole (shin) -- were limited in practice, as was safety Steve Gregory, who played his first game Sunday since suffering a broken thumb before the team's bye. Dennard was the only defensive back to miss Sunday's game in Houston.

Tight end Michael Hoomanawanui (knee), who practiced for the first time since leaving a Week 11 game, was limited.

New additions to the injury report include wide receiver Kenbrell Thompkins (hip) and offensive tackle Will Svitek (knee).

As for the Browns, the Patriots' opponent on Sunday: QBs Brandon Weeden and Jason Campbell, each dealing with concussions, sat out Wednesday's practice. Coach Rob Chudzinski told New England-area reporters on a conference call Wednesday that he has still not made a decision about who will start at quarterback, with Alex Tanney and recently signed Caleb Hanie among the possibilities.
