After the game, Welker was asked if the ankle would be OK.
"Yeah, I think so," he said. "We'll see. We'll evaluate it in the morning. It's hard to tell right after it happens. We'll evaluate it as the week goes on."
"It just kind of got stuck in the turf," Welker said of his foot.
Welker took himself out of the game and was later seen with his left leg elevated as a member of the team's training staff applied tape. After putting his cleat back on, Welker walked along the sideline, and at one point, he was seen smiling as he talked with Brady.
Welker, the team's leading receiver this season, finished with six receptions for 48 yards.
The Patriots have their bye this week and return to action Nov. 11 against Buffalo.
