The Arizona Cardinals lost a key cog in their defensive front on Monday when Darnell Dockett went down with a season-ending injury. The starting defensive tackle was carted off the field during practice with an injury that has been diagnosed as a torn ACL, the team announced.
Dockett grabbed his right knee after suffering the injury during an 11-on-11 drill.
The 33-year-old has been one of the most durable players in the NFL over the past decade. Since being drafted by Arizona in 2004, Dockett has only missed a total of two games over the past 10 seasons. Dockett has played in a 158 of 160 career regular season games with Arizona and started in 156 of those.
The three-time Pro Bowler tallied 4.5 sacks last season, his highest total since 2010. Dockett's play helped propel the Cardinals defense to a sixth overall NFL ranking in 2013.
The injury to Dockett means backup Frostee Rucker will likely move into the starting lineup. Rucker played in all 16 games last season for Arizona, but only started one.
