The Facts: Following up on the ongoing story. ... Per a league source, the Patriots and Lewis currently are awaiting the results of an MRI conducted Sunday night on a knee Lewis injured during Sunday's win over Washington.

Diehards Line: Lewis has only 234 yards rushing on the season, but he has added 388 receiving yards. He has four total touchdowns. His modest numbers understate his impact on the offense, providing a degree of elusiveness none of the team’s other tailbacks possess. Indeed, the ordinarily zero-tolerance Bill Belichick has put up with fumbles and drops from Lewis, given his unique skill set. ... Stay tuned. We'll be watching for more on this one -- although there's no guarantee the Patriots will shed more light than necessary on the situation.
