The Browns have reportedly added some offensive line depth via waivers.
Seymour (6-4, 301) appeared in all four exhibition games for the 49ers. A Vanderbilt product, the 24-year-old Seymour was a 2013 seventh-round pick of Seattle.
Hauptmann (6-3, 300) rejoins the Browns after the Seahawks signed him off of Cleveland’s practice squad last September. Hauptmann, 23, is a second-year pro from Florida International.
And that’s not it for Browns roster moves. The club has added former 49ers running back Glenn Winston on waivers, according to Matt Maiocco of CSNBayArea.com. The Browns will have to open roster spots for Seymour, Hauptmann and Winston.
