Westbrooks, a restricted free agent, re-signed with the Rams on Monday, Myles Simmons of the team's official site reports.
Westbrooks has tallied at least 19 tackles and two sacks for the Rams in both of the last two seasons. Now that ESPN reported he won't be facing legal charges from an incident last month, Westbrooks can set his sights on protecting his starting defensive end job this summer.
