Paulsen will undergo surgery Monday due to turf toe on his right foot. He suffered the injury during practice on Aug. 6.
He is the second Redskins tight end to be ruled out for the season. Niles Paul, the projected starter at the position, is out for the year after fracturing his ankle during Washington's first preseason game.
In his career, Paulsen has 79 catches for 801 yards in 75 games.
Redd Jr., who would have been entering his second season, suffered a torn ACL and MCL in his right knee during the third quarter of the Redskins' first preseason game.
In his first season, Redd played in 15 games, carrying the ball 16 times for 75 yards and a touchdown.
