Beckwith was one of four players cut by San Diego as they got down to the 75-man roster deadline Tuesday afternoon. Beckwith was leading the AFC West with 18 tackles through three games.
The other three players cut by San Diego were receiver Gary Banks, guard Lee Grimes and running back Marcus Mason. Prior to the season, Banks and Mason were considered players who could make a push to make the roster.
San Diego officially placed rookie linebacker Donald Butler on the injured reverse. He suffered an Achilles injury early in camp and is lost for the season. San Diego signed punter Glenn Pakulak to take some late camp pressure off of standout punter Mike Scifres.
UPDATE: San Diego claimed cornerback Fred Bennett off waivers from the Houston Texans. He is a fourth-year player from South Carolina, who stated three games last season. He will vie for a roster spot. To make room for Bennett, San Diego cut defensive lineman Ryon Bingham, who has been plagued by injuries.
