One day after cornerback Perrish Cox signed with the Seattle Seahawks, he is looking for work again.
The Seahawks released Cox, and they promoted cornerback DeShawn Shead from their practice squad to the active roster Wednesday.
The Seattle Post-Intelligencer reported that free agent cornerback Antoine Winfield worked out with the Seahawks this week, and that Seattle might be close to signing him. On Monday, the team also worked out former Seahawks cornerback Marcus Trufant, another free agent.
Cox posted on his Twitter account: "Its reason 2 everything, just know it was not about my play, at all! But i cant and wont say"
The maneuvering over the cornerback position is a result of one announced suspension and one pending suspension.
On Tuesday, cornerback Walter Thurmond officially dropped his appeal of a four-game suspension he received for violating the league's substance-abuse policy.
Injured starting cornerback Brandon Browner reportedly faces a one-year ban for violating the league's substance-abuse policy. According to NFL.com, Browner's appeal was heard Wednesday.
Shead, 25, was an signed by the Seahawks in April 2012 as an undrafted free agent. He spent most of 2012 on the practice squad, never getting into a game, and he spent all of the current season on the practice squad.
Cox, 26, was a fifth-round pick by the Denver Broncos in 2010, and he was out of football in 2011 due to off-field issues. He signed with the San Francisco 49ers in 2012 and played in 25 games as a reserve before being released Nov. 12. Cox has 71 tackles and one interception in 40 career games, including nine starts.
Byron Maxwell is expected to start at cornerback opposite Richard Sherman on Monday against the New Orleans Saints. Jeremy Lane will fill the nickel role.
"I'm getting more reps that's about it, but I take everything the same as I've been doing," Maxwell said. "Everything is the same."
Seahawks safety Earl Thomas said of the uncertainty in the secondary, "I take the same chip on my shoulder whether we have the guys we started the season with or the second string because they're just as good. Nobody knew about Richard Sherman until he got his opportunity. It's just like that.
"In this defense we have techniques at every aspect as far as being a defensive back. When you play corner, you know what to expect. Kick step, stay on top, our defense is really easy."
