Marshall (concussion) didn't practice Wednesday, Joe Person of The Athletic reports.
The rookie entered the concussion protocol Week 6 and missed a Week 7 loss to the Giants. With No. 4 receiver Brandon Zylstra (hamstring) on injured reserve, Keith Kirkwood and Shi Smith both earned playing time in Marshall's absence last week, combining for seven targets and 49 snaps. Both players could help fill in for Marshall again this Sunday at Atlanta if he can't clear protocol by the end of the week.
