Patriots starting left tackle Nate Solder missed Wednesday's practice due to a concussion, according to the team's practice report.
Solder did not miss any snaps during the Patriots' Week 14 win over the Browns, and it is unclear when the injury took place.
He was one of two Patriots to miss practice on Wednesday, as rookie wide receiver Aaron Dobson missed his seventh consecutive practice after suffering a foot injury during a Week 12 win over the Broncos.
Solder will need to pass NFL concussion protocols to return to practice. His status for this Sunday's game in Miami is not known at this time.
Cornerback Alfonzo Dennard, who has been previously limited by a knee injury, was also limited by a shoulder injury, which he suffered on Sunday against the Browns.
Cornerbacks Aqib Talib (hip), Kyle Arrington (groin) and Marquice Cole (shin) were also limited, as was quarterback Tom Brady (right shoulder). Brady has been limited in practice during previous parts of the season, though the issue has not seemed to limit him at all during games.
