Avril has recorded eight or more sacks in four of his last five seasons (all with Seattle) and has been important part of the Seahawks' menacing front seven. His loss sets up to have a significant impact on Seattle's defense, allowing offenses to divert more attention to opposite end Michael Bennett and bringing down the unit's overall ability to rush the passer.
Clark is no rookie, though. In his first two seasons, he recorded 63 tackles, 13 sacks and two forced fumbles. The replacement notched four tackles in the win over the Colts, including being part of a split tackle for loss.
