Chamberlain tore an ACL on Friday night against the Jaguars, via WWLTV.com. He’s out for the year.
The fifth-year veteran followed former Rams head coach Steve Spagnuolo to New Orleans in the offseason, signing a three-year deal as a free agent in March. He was listed as a third-stringer in the team’s most recent unofficial depth chart.
Chamberlain, who entered the league as a seventh-round pick in 2008, started 13 of 16 games for the Rams in 2011.
