Concepcion, who was helped off the field Sunday, appeared to be having trouble putting pressure on his right leg, Ross Jackson of Louisianasports.net reports.
Per Mary Kay Cabot of The Cleveland Plain Dealer, it was a non-contact injury for Concepcion, who had caught both of his targets in the game for 11 yards. For now, Denzel Boston, Jerry Jeudy, Tylan Wallace, Malachi Corley and Isaiah Bond are Cleveland's available WRs.
