Detroit Lions QB Matthew Stafford (ankle) remained out of practice Thursday, Dec. 31, due to a sprained ankle, but head coach Darrell Bevell is optimistic Stafford will start Sunday against the Minnesota Vikings. ‘You’re going to have to convince me a lot that this guy’s not going to go,’ Bevell said Thursday. ‘He’s as tough as they come, tough as nails, he wants to be out there, and I think really those two things are probably the most important, if the guys want to. I mean, I always say this, I always say that your mind’s a powerful thing and you can do a lot if you just believe in that. And the guy wants it, so there’s not a doubt in mind that he won’t make it happen, but obviously we’re going to continue to go through the week and see how it goes.’
