Darnell Dockett, a mainstay on the Arizona Cardinals’ defensive line for the past decade, is out for the season due to a knee injury.
The Cardinals announced Monday night that Dockett sustained a torn ACL in his right knee during practice earlier in the day. The injury will require season-ending surgery.
Dockett has been one of the central figures of the 49ers' NFC West rivalry with the Cardinals. And after learning of Dockett's injury, 49ers quarterback Colin Kaepernick responded via Instagram.
"Prayers up for @dockett90 it hurt me to hear about this!" Kaepernick wrote. "Great respect for him because of the way he works!"
Dockett, who missed just two games in his first 10 NFL seasons, has been a powerful presence since arriving with the Cardinals as a third-round draft pick in 2004. Known primarily for his run defense, Dockett has also recorded 40.5 sacks in his career.
Led by a stout defense last season, the Cardinals finished 10-6 and barely missed advancing to the NFC playoffs. The Cardinals are expected to challenge the 49ers and Seattle Seahawks this season for the NFC West title.
