Patriots running back Shane Vereen was absent from practice Friday for unknown reasons, per ESPN. He was not listed in their previous injury reports and had participated in the team's three previous sessions this week in preparation for the Week 8 game against Chicago.
Vereen, who dealt with a shoulder issue early in the season, is coming off his most productive game of 2014. He rushed for 43 yards on 11 carries and added five catches for 71 yards and his first two receiving touchdowns of the year in Week 7 against the Jets.
