Defensive end Chris Long has agreed to a four-year extension with the St. Louis Rams that will keep him under contract through the 2016 season.
Financial terms of the deal were not available, but the contact is believed to be "huge," according to a Fox Sports report.
He originally signed a six-year $56.5 million contract with $29 million guaranteed.
Long, 27, had 13 sacks last season and has 30.5 sacks in his four-year NFL career.
Long is the son of former Raiders defensive end Howie Long.
