RENTON, Wash. (AP) - The Seattle Seahawks have released veteran defensive tackle Ahtyba Rubin, backup quarterback Trevone Boykin and fullback Marcel Reese as part of their roster moves to reach the 53-man limit.

Seattle announced its roster moves on Saturday night, several hours after the NFL deadline of 4 p.m. ET for rosters to be set. Seattle's moves included wide receiver Kasen Williams and cornerback Pierre Desir being waived after both had been standouts in training camp.

The decision to release Boykin means Seattle will go into the season with just veteran Austin Davis as the backup QB to Russell Wilson. Boykin had served as Wilson's backup a year ago, but was inconsistent during the preseason.

Seattle also made a pair of trades, sending defensive end Cassius Marsh to New England in exchange for fifth- and seventh-round picks and acquiring offensive lineman Isaiah Battle from Kansas City in exchange for a conditional draft pick.

Here are all the roster moves:

Traded (pending physicals)

CB Tramaine Brock to Minnesota for 2018 seventh-round draft choice
