With the move of T Russell Okung to the short-term injured reserve list on Friday, the Seattle Seahawks have a vacant spot on their roster. Okung will not count against the team's 53-man roster limit while on the injured reserve list.

A source confirmed that the Seahawks would be adding G/T Caylin Hauptmann off the Cleveland Browns practice squad.

Hauptmann had tweeted Saturday that he was heading to join the Seahawks.

The move was not listed on the league's transaction report for Saturday. It means that Hauptmann's addition will not be made official until Monday and he will not be able to play against the Jacksonville Jaguars. The Seahawks will have just 52 players available for Sunday's game.

With Okung's move to injured reserve and the release of T Michael Person last week (Person was claimed off waivers by the St. Louis Rams), the Seahawks were a bit thin along the line with just eight offensive linemen on their active roster.

Hauptmann is a rookie out of Florida International that spent the preseason in Cleveland. He appeared in all four preseason games while making one start at left guard against the Chicago Bears in the Browns' preseason finale.

In addition, the Seahawks released receiver Bryan Walters from their practice squad on Saturday.
