Detroit Lions quarterback Matthew Stafford is reportedly dealing with quad and ankle injuries.
On Monday, Ian Rapoport of NFL.com reported the Lions are still "optimistic" Stafford will start Sunday's game against the New Orleans Saints despite the setbacks.
It would be a difficult blow for Stafford if he did miss time, considering he has been one of the most durable quarterbacks in the league in recent years following the difficult early portion of his career. He played a full 16-game schedule every season from 2011 through 2016 and threw for more than 4,000 yards and at least 20 touchdowns in each.
