Lane suffered a broken arm on an interception return in the first quarter of Seattle's Super Bowl loss against New England. Lane torn his ACL on the same play, the Seattle Times reports.
Lane spent the first half of the 2014 season on injured reserve with a groin injury. He was limited to seven games, registering 13 tackles and one fumble recovery.
Hill played in 13 games, recording 19 tackles, 5.5 sacks and an interception.
It allowed only six points on 216 yards in Week 16, recording four sacks and one interception. Of the Seahawks' 33 sacks this season, 20 have come in their last five games.
Clearly, they had a favorable matchup in this one, but they also shut down the Eagles in Week 14. You don't have any reason to shy away from the Seahawks DST against St. Louis in Week 17.
Avril was set to become a free agent at the end of the season before signing an extension. Since joining the Seahawks in 2013, the 28-year-old pass-rusher totaled 40 tackles, 12 1/2 sacks and six forced fumbles over 29 games.
The Seahawks mostly failed to make many big plays, but the 49ers just couldn't get anything done against them offensively. The 49ers managed just 245 yards of total offense in the game, and though they failed to come away with any turnovers, the Seahawks did sack Colin Kaepernick six times en route to 16 Fantasy points.
The Seahawks have found their way on defense of late, averaging 19.0 Fantasy points per game over the last four. They will look to keep it up in Week 16 against the Cardinals, and should be viewed as a must-start unit.
