Most notably, the team cut ties with quarterback Rex Grossman and wide receiver Charles Johnson. Among the waiver claims the Browns made was wide receiver LaRon Byrd, a big (6'4) target who was waived by the Cowboys on Saturday.
Johnson is practice-squad eligible once he clears waivers. He was signed by the Browns last season from the Packers practice squad, then found to have a torn ACL.
Wide receiver remains a problem area for the Browns after losing Josh Gordon to a season-long suspension. The team cut veteran Nate Burleson on Saturday.
Grossman was signed in mid-August to help tutor Brian Hoyer and Johnny Manziel in new coordinator Kyle Shanahan's offense. He made one brief preseason appearance, in last Thursday's preseason finale.
Teams began finalizing their practice squads on Sunday, too. The Browns won't be adding Garrett Gilkey or MarQueis Gray to their practice squad after waiving them Saturday. Gray was claimed by the Vikings and Gilkey was claimed by the Buccaneers.
The team also claimed offensive linemen Ryan Seymour and Caylinn Hauptmann off waivers. Neither has ever played in an NFL game. Running back Glenn Winston (San Francisco) was also added to the team via waivers.
To make room on the roster, the Browns also released offensive linemen Karim Barton and Martin Wallace.
