No major injury concerns for Ravens

Bernard Pierce was limited in Wednesday's practice with a knee injury but the Ravens backup running back expects to play Sunday in the AFC Championship Game at New England.

Beyond that, the Ravens' key contributors remain relatively healthy. The only player who didn't practice was reserve cornerback Asa Jackson (thigh). Three backups -- running back Anthony Allen (head), center-guard Gino Gradkowski (head) and receiver David Reed (thigh) -- were limited.

There were 16 players listed as full participation.

For the Patriots, tight end Rob Gronkowski (forearm) isn't expected to play. Defensive end Chandler Jones (ankle) and running back Danny Woodhead (thumb) were limited in practice.
