Matavao was diagnosed with a knee injury following the Saints' 34-0 preseason loss to the Rams on Saturday, Matthew Paras of The New Orleans Times-Picayune reports.
It's unclear when Matavao tweaked his knee, but he'll undergo more tests over the coming days to determine the severity of the injury and whether he'll be available for the Saints' preseason finale against the Cowboys on Friday. The 2025 seventh-rounder finished Saturday's game with three catches on as many targets for 34 yards.
