Freeman is dealing with his second concussion of the season and Schefter adds that he may end up missing more than just one week.

Overall this season, Freeman has rushed for 515 yards and five touchdowns while also catching 19 passes for 137 yards. Freeman, who played his collegiate football at Florida State University, was originally selected by Atlanta in the fourth round (103rd pick overall) of the 2014 NFL Draft.

He played only scarcely during his rookie campaign, carrying the ball 65 times for 248 yards and one score while hauling in 30 receptions for 225 yards and another touchdown.
