Seahawks waived WR Bryan Walters.
Packers placed NT Khyri Thornton (hamstring) on injured reserve.
Thornton would have been in the mix to help replace B.J. Raji, but went down in Green Bay's final preseason game and is done for the season. A third-round pick, Thornton will push for playing time in 2015. Josh Boyd is expected to open the season as the Packers' starting nose tackle.
Packers waived RB LaDarius Perkins, C Garth Gerhart, DT Carlos Gray, RB Michael Hill, LB Adrian Hubbard, S Tanner Miller, TE Justin Perillo, DE Luther Robinson and OT Jeremy Vujnovich.
An undrafted free agent out of Mississippi State, Perkins rushed 31 times for 93 yards (3.0 YPC) this preseason, adding two catches for 21 yards and a score as a receiver. He's a candidate for the practice squad.
49ers coach Jim Harbuagh expects G/C Marcus Martin (knee) to miss six weeks.
It's a slight upgrade from his initial two-month timetable. Martin will avoid injured reserve, but likely won't return before Week 7.
Browns placed WR Marlon Moore on the reserve/suspended list.
Moore is suspended for the first game of the season and won't count against the Browns roster. He's currently the No. 6 receiver behind Charles Johnson and Taylor Gabriel and isn't guaranteed a spot when he returns.
49ers placed FB Will Tukuafu (concussion) on injured reserve.
Tukuafu could ultimately be released with an injury settlement. Bruce Miller will open the season as the 49ers' starting fullback.
49ers placed CB Kenneth Acker on injured reserve, ending his season.
A sixth-round pick, Acker will be stashed on the I.R. list. He'll return to compete for a roster spot in 2015.
49ers waived/released WR L'Damian Washington, CB Darryl Morris, OG Al Netter, DL Lawrence Okoye, Ot Michael Philipp, NT Mike Purcell, OG Ryan Seymour, RB Alfonso Smith, LB Chase Thomas, S Bubba Ventrone and RB Glenn Winston.
An intriguing size/speed prospect out of Mizzou, Washington couldn't crack San Francisco's crowded receiver corps. He's a candidate for the practice squad.
