Matthew Stafford said doctors have not given him a firm timeline on how many games he should expect to miss with the back injury that has kept him out the last two weeks. "There’s nothing firm, set anywhere," Stafford said on The Mitch Albom Show on WJR 760-AM. "I think for me it’s a fluid situation and just something I’m monitoring and trying to make sure that when I’m back out there I’m ready to go and obviously, l’m doing, like I said earlier, everything I possibly can to get out there as fast as I can." Stafford fractured bones in his back late in the Lions' Week 9 loss to the Oakland Raiders and was held out of losses to the Chicago Bears and Dallas Cowboys the past two weeks. ESPN reported on Sunday that doctors told Stafford he had a six-week injury , and other reports suggested he could miss the rest of the season. Asked about that timeline Monday, Stafford did not directly dispute it. "I haven’t talked to anybody about any of that stuff, so I’m not really sure to be honest with you where they’re getting that information," he said. "It's collaborative effort between myself, Coach and the doctors just to figure out when is appropriate and when is the best time for me to get back out there. But rest assured I’m doing everything I can to be back as soon as possible. And nothing’s worse for me than standing on the sideline, not being able to impact the game, so I’m doing everything I can to get back." Lions coach Matt Patricia said at his news conference Monday that Stafford remains "week to week." He declined to say if he thought Stafford will play again this season. At 3-6-1, the Lions are in last place in the NFC North and on the verge of being mathematically eliminated from the playoffs. The travel to 1-9 Washington this week and host the 4-6 Chicago Bears on Thanksgiving next week. If the Lions are officially out of playoff contention in December, they may have to decide whether to rest Stafford for the rest of the season or let him return for meaningless games. "We’re week by week with him," Patricia said. "He’s the same guy every day. He comes in ready to go and works hard, so we’ll see how it goes as we progress week by week." Jeff Driskel has played well in Stafford's absence, and Stafford said in his radio interview he's "trying to do everything I can to support Jeff" and the rest of his teammates during games, which he said are "frustrating" to watch from the sideline. "It’s uncomfortable for me," Stafford said. "I’m used to having the pads on and knowing what I’m going to do and what I’m going to say and where I’m going to be and there’s a little bit of the unknown for me when I’m not in those situations. But I’m doing the best I can to try and do what I think is going to help us win, and my role is obviously significantly different without a set of pads on but I’m trying to help anyway I can."
