The Raiders activated outside linebacker Aaron Curry to the 53-man roster Tuesday, doing so before the deadline to make a decision on how to proceed.
The options were: activate Curry, waive him or place him on season-ending injured reserve. Curry was at the tail end of a 21-day evaluation period in his return from the physically unable to perform list.
The Raiders waived linebacker Vic So'oto to make room for Curry on the roster. Curry is eligible to play against the Baltimore Ravens on Sunday.
Curry missed some of the offseason workouts, all of training camp and the first eight games while recovering from sore knees. At one point, he went to Southern California for treatments from a specialist.
It's likely the Raiders will use Curry on special teams and as a backup at all three linebacker positions, at least in the short term as he gets back into football shape.
The Raiders will have to make another roster move if they activate cornerback Ron Bartell in time for Sunday.
Bartell is back at practice, but he doesn't count on the 53-man roster because he is in his reacclimation period after being placed on injured reserve earlier this season. He suffered a shoulder injury in the season opener and missed the past seven games.
