Alex Smith has concussion
Smith was injured in the fourth quarter after he caught a short pass over the middle and was struck in the head by the knee of a Bengals tackler. The 30-year-old Smith walked off the field under his own power, but was taken by ambulance to a Cincinnati hospital. His agent, Kevin Robinson, said Smith was checked and released and driven back to Cleveland by car.
The Browns (0-2) said Smith is listed as day to day.
Smith had four catches for 30 yards in Cleveland's 34-27 loss. He is in his third season with the Browns.
