Allen was released by the Raiders on Tuesday, ESPN's Field Yates reports.
EDGE Analysis
Allen was limited to five games this season after a knee injury kept him out for most of the 205 campaign. As ESPN's Adam Caplan notes, Allen was a cap casualty in this case given that his $4.9 million base salary would have become fully guaranteed on Feb. 10 if he was still on the roster. The 28-year-old Allen has seven interceptions over the course of his six-year career and is now a free agent.
