Siverand posted the statement on Twitter:
The 23-year-old Oklahoma State product signed with the Seahawks as an undrafted free agent. The rookie spent less than four months with the organization.
Seattle head coach Pete Carroll didn't comment on Siverand directly but discussed his message to players amid the coronavirus pandemic with NBC Sports' Peter King.
"Rule number one here: Always protect the team. I'll convey the degree of discipline we need here, every day," Carroll said. "I'll tell them your conscience is important; your conscience has to guide you."
Siverand started his college career at Texas A&M in 2015 before transferring to OSU in 2018. He made a limited impact across both stops.
He recorded 17 total tackles, one forced fumble and no interceptions in 13 collegiate appearances. He added one catch for 16 yards while operating as a wide receiver with the Aggies.
Siverand, a long shot to make the Seahawks roster, has remained a free agent since being let go.
