Vikings CB Cedric Griffin tore the ACL in his right knee in Monday night's loss to the Jets, an MRI on Tuesday revealed. PFW correspondent and Minneapolise Star-Tribune writer Judd Zulgad reported the news.
Griffin left the game in the second half and did not return.
Last season, Griffin hurt his other knee, tearing his left ACL in the NFC championship game. He returned to the lineup from that injury in Week Three.
Chris Cook, who would be the top candidate to replace Griffin in the starting lineup, missed Monday's game with a meniscus injury, although he could return this week. Other options include Asher Allen, who replaced Griffin Monday night, and Lito Sheppard.
The way we see it
For a team that is already 1-3, the news just keeps getting worse for the Vikings. The team will need as many healthy defensive backs as possible in the coming weeks, when they face the high-octane offenses of Dallas, Green Bay and New England.
