Vikings defensive line reunited

Posted by ESPN.com's Kevin Seifert

The Minnesota Vikings finally have gotten all four starters on their celebrated defensive line back on the field.

Tuesday, nose tackle Pat Williams was cleared for team drills after previously taking limited work to protect his surgically-repaired elbow.

On Wednesday, the Vikings activated left end Ray Edwards (back) from the Physically Unable to Perform list. Edwards participated in individual drills Wednesday morning and is on track to start doing team work soon.

Edwards, Pat Williams, Kevin Williams and Jared Allen form what many consider the best defensive line in the NFL.
