Moses has started every game at right tackle for Washington since the 2015 campaign, amassing 104 total appearances since entering the NFL as a third-round pick in 2014.
The 30-year-old is coming off the best season of his career, according to PFF, but he saw Washington add multiple offensive tackles this offseason. The team signed free agent Charles Leno and recently drafted Samuel Cosmi in the second round.
Moses allowed five sacks and 13 quarterback hits while committing six penalties last season, according to PFF.
The Virginia product is signed through the 2022 campaign and is set to make $7.75 million this year, per Spotrac.
