The Ravens already had outside linebacker Terrell Suggs go down with an Achilles tendon injury.
Now, it appears one of the players vying to replace him has torn his Achilles tendon.
Michael McAdoo reportedly suffered a torn Achilles tendon during organized team activities on Thursday, according to Aaron Wilson of the Carroll County Times.
He reportedly had surgery on Friday and is expected to miss the entire season.
The team has not confirmed the report.
McAdoo, 6-foot-7, 245 pounds, is a pass rusher out of North Carolina who spent last season on injured reserve with a knee injury. He has not been able to get on the football field in two years because he missed the 2009 college season due to an NCAA suspension.
Before suffering the Achilles tendon injury, McAdoo told BaltimoreRavens.com on Wednesday that he felt like he was "further ahead" than he expected this offseason. McAdoo was competing with Paul Kruger, Courtney Upshaw, Sergio Kindle and Albert McClellan for a spot at outside linebacker.
