Seahawks receiver Sidney Rice is retiring, per league source.

Between knee problems and concussion concerns it's time to say goodbye to Sidney. He's calling it a career. His best season came in 2009 when he was with the Vikings and he and Brett Favre connected for 83 receptions, 1,312 yards, and eight touchdowns. Since then, he's been a mess with injuries and has missed almost as many games as he started. Be well, Sidney. Vaya con dios, amigo.ANALYST: Howard Bender
