Former New York Giants cornerback Terrell Thomas announced his retirement after six seasons in the NFL.

Thomas, a second-round pick from Southern Cal in 2008, started every game at cornerback for the Giants in 2009 and 2010 before torn knee ligaments ended consecutive seasons — but not his career.

Thomas came back from season-ending knee injuries in 2011 and 2012 to play a full season in 2013.

—Josh McCown was released by the Tampa Bay Buccaneers but plans to continue playing in the NFL.

The 35-year-old quarterback signed a two-year, $10 million deal with the Buccaneers to be the team’s starter in 2014, but he struggled to stay healthy. He started 11 games with 11 touchdowns and 14 interceptions. The Buffalo Bills, Baltimore Ravens, Tennessee Titans and New York Jets are among the possible suitors for McCown.

Tampa Bay owns the No. 1 overall pick in the draft and is widely expected to select a quarterback in the first round for the second time since 2009 (Josh Freeman, Kansas State). According to NFLDraftScout.com, Florida State’s Jameis Winston and Oregon’s Marcus Mariota are the top two prospects at the position and likely to be drafted in the top five.

—Kevin Warren, promoted Thursday from executive vice president to chief operating officer of the Minnesota Vikings, said he would welcome the return of running back Adrian Peterson.

It’d be good for us, it’d be good for all the Vikings fans, it’d be good for our community and it’d be good for the NFL.”

Warren will oversee all aspects of the Vikings business operations and create strategic efforts for all departments in this his 11th season with the team and 17th in the NFL. Warren reports directly to Wilf. e was instrumental in stadium construction plans and oversaw design concepts for the team’s new billion-dollar home and represents the team at all NFL meetings.
