"It's a medical decision and medical people will make that decision," Goodell said, according to the Detroit News. "The medical care that our players get is extraordinary. Jahvid has seen a number of doctors outside the Lions' organization, neutral doctors, and they are all focused on his care and to make sure they make the best decision for Jahvid Best."
Best has not been cleared for contact since suffering a concussion, his second of the season, in Week 6 against the San Francisco 49ers.
"The only thing I will say is we're measuring Jahvid in weeks, not days," Schwartz said, according to MLive.com. "He's not day-to-day."
