Hall, 34, played five games for the Washington Redskins last season. Originally the eighth overall pick by the Atlanta Falcons in the 2004 draft, he spent four seasons in Atlanta, eight games with the Oakland Raiders in 2008, and the last 9.5 seasons in Washington.
He'd suited up for just eight games over the past two years and hadn't played a full 16-game schedule since the 2013 season.
The outspoken corner appeared in three Pro Bowls and won the Fastest Man competition at the 2005 event. He finishes his career with 43 interceptions, 11 forced fumbles, two sacks, and 811 combined tackles across 171 games. He played in a total of four playoff contests with Washington and Atlanta.
Known for his intensity, Hall was fined $10,000 while with the Falcons in 2007 for carrying a poster of then-teammate Michael Vick onto the field and wearing "MV7" in the shade underneath his eyes. Vick, Hall's former Virginia Tech teammate, had been sentenced to 23 months in prison on dog-fighting charges.
He was fined another $30,000 in 2012 for removing his helmet and confronting a referee in a game against the Pittsburgh Steelers while playing for Washington.
The Falcons traded Hall to the Raiders for second-round and fifth-round picks following the 2007 season. He then signed a six-year extension worth $23 million guaranteed with his new team. However, he lasted just eight games before being released due to poor performance. He was signed to a one-year contract by Washington shortly after, and then signed a new six-year, $54-million deal the following offseason, according to Over The Cap.
