"The Lions continue to have no timetable on the return of running back Jahvid Best, who has missed the past two games with a concussion.

"We've had some players come back quickly, some players that lasted a little bit longer," coach Jim Schwartz said Monday. "But the one thing we'll be sure to do is be objective and listen to the people that are expert in those decisions.

"I say it all the time, but I'll say it again: It's not something that you can put tape around, it's not something that you can tough out. It's a situation that we have to be conservative, and I think it's good for Jahvid, it's good for the NFL.""
