Though the Detroit Lions are basically done for the season, injured quarterback Matthew Stafford isn’t ready to call it quits.With their playoff hopes dwindling with each passing week, the 3-6-1 Lions do have hope when they go on the road to face the 1-9 Washington Redskins on Sunday. But they’ll likely do it without Stafford, who sat out practice again Wednesday and whose status is considered week to week with fractured bones in his back.For any doubters wondering why Stafford would even consider playing the rest of the season, the QB had a simple answer.”Because this is what I do,” Stafford said Wednesday on the team’s website. “… This is what I love to do. I love playing football. I appreciate all the hard work that all the guys in this locker room and in this organization put into going out there and trying to win games on Sunday and I love being a part of that.”Before sitting out the Nov. 10 game at the Chicago Bears, Stafford had started 136 consecutive games — the sixth-longest streak for a quarterback in NFL history.Though Stafford practiced before the Bears game, a recent scan of his back showed problems that have kept him from practicing the last two weeks.Backup Jeff Driskel started against the Bears and was back under center Sunday against the Cowboys.
