Bell's teammate Vance McDonald (concussion) has been ruled out for Sunday's game against the Browns, Cam Inman of the San Jose Mercury News reports.
Primarily a quarterback (and red-zone running specialist) until his final season at the University of Oklahoma, Bell was selected by the 49ers in the fourth round of the 2015 NFL Draft. He hasn't drawn enough targets to make any meaningful conclusions, but there's little question that he's an excellent athlete, and the 49ers don't exactly have a deep receiving corps. Of course, with Vance McDonald sidelined by a concussion, there's a decent chance Bell's promotion will only last one week.
