Bednar isn't available out of the Pittsburgh bullpen for Sunday's series finale with the Nationals while he tends to an unspecified injury, Jason Mackey of the Pittsburgh Post-Gazette reports.
According to Mackey, Bednar isn't dealing with an injury involving his throwing arm, but the Pirates haven't offered any further specifics on what's ailing the right-hander. With three saves in his last seven appearances, Bednar appears to have emerged as the Pirates' primary closer, but he now looks to be at risk of missing time while he tends to the injury. The Pirates are said to be considering placing him on the 10-day injured list.
