Wallace (hamstring) was ruled doubtful to return to Sunday's game against the Colts, Jonas Shaffer of TheBaltimoreBanner.com reports.
Wallace did not record a statistic before exiting Sunday's game with a hamstring issue. The third-year wideout has been primarily limited to a role on special teams so far this season; however, with Odell Beckham (ankle) already inactive, the Ravens will be left with four available wideouts for the time being.
