FOXBOROUGH, Mass., -- The Patriots are practicing inside the Dana-Farber Fieldhouse on Saturday afternoon and rookie left tackle Sebastian Vollmer was not present for the start of the session, casting doubt on his availability for Monday's game in New Orleans.
Vollmer sustained a head injury in last Sunday's win over the Jets, although he returned to action in that game.
Vollmer, who did not practice Friday, has started the team's last five games.
If Vollmer does not play Monday, veteran Matt Light would likely slide back in at left tackle. Light has been out since injuring his right knee in the second half of the team's loss in Denver Oct. 11, but appears close to a return. Swing tackle Mark LeVoir is another possibility.
