Heading into their bye week on a 2-3 record, the Oakland Raiders are no longer the laughing stock of the NFL and have made huge strides under head coach Jack Del Rio.
One of the team's biggest areas of success in 2015 has been their ability to stop the run - they've actually given up the sixth-fewest yards on the ground to opponents.
Unfortunately, when the team returns from a week away from the gridiron, they might not be such a force in that area. That's after a report today revealed Oakland fear defensive end Justin Tuck has suffered a serious injury.

NFL Media's Ian Rapoport had the latest on the situation:
The Raiders themselves don't exactly seem optimistic when it comes to the 32-year-olds immediate prospects. Indeed, when asked about Tuck's situation, Del Rio told reporters this week that it's "not good."
Tuck has one sack and seven total tackles through the first five weeks of the 2015 campaign, and the veteran has been an important presence on what is a young Raiders defense.
Should he miss the rest of the campaign, it would be a huge blow for the franchise after what has been, in the majority, a positive start.
Tuck is currently in the middle of the second year of a two-year deal in Oakland so, should he have played his last game of 2015, it could well be the last for the franchise altogether.
The Raiders hierarchy and the player himself will, of course, be hoping that the prognosis improves over the next few weeks.
