FOXBOROUGH, Mass. -- Running back Shane Vereen was not spotted at the start of the Patriots’ practice on Friday.

Vereen has not been listed on the team’s injury report, so it was unclear why he was missing from practice. He was in attendance for the three other practices held this week on Tuesday, Wednesday and Thursday.

Vereen had dealt with a shoulder injury earlier in the season that had him listed as questionable for the team’s Week 3 game against Oakland.

Defensive end Chandler Jones missed his fourth practice of the week with a hip injury and is unlikely to play this Sunday against the Bears. Jones is reportedly out for one month while he recovers.

While there was a sighting of defensive tackle Alan Branch in the locker room on Thursday, Branch was not seen at Friday’s practice. The team has not officially announced the signing of the 6-foot-6, 325 pound Branch.

The Patriots were wearing sweats and shells at practice.
