The Redskins have been notified that Sean Taylor passed away Tuesday morning at Jackson Memorial Hospital in Miami.
He was 24 years old.
"This is the worst imaginable tragedy," Redskins owner Daniel M. Snyder. "Our thoughts and prayers are with Sean's family."
Taylor was injured Monday in a shooting at his residence in Miami and did not survive.
"We're going to miss him very, very much," Snyder added.
Taylor was reportedly shot by an intruder at his residence. His girlfriend Jackie Garcia and 18-month-old daughter Jackie were also at the residence, but were unharmed in the incident.
Mourning has begun at Redskins Park. Tuesday is the player's day off, so only a handful of Redskins were at the facility. Those who were there were stunned and grief-stricken.
"He will truly be missed by all of us," quarterback Jason Campbell said. "We hold him close to our hearts. It's just a tough situation right now."
Head coach Joe Gibbs said that Taylor had matured in the last year, in part because of the birth of his daughter Jackie.
"Sean had a great relationship with the Lord and the feeling is that he's going home," he said. "It's hard for us, because we're here and we're going to miss him--not as a player, but as a person."
The team coordinated a memorial for Taylor in front of the guardhouse leading into Redskins Park.
The No. 21 was painted in the grass near the front entrance. Nearby, fans began laying flowers underneath a tree.
By early evening, hundreds of fans had paid their respects.
In addition, the No. 21 was painted on the plaza in front of the Redskins Hall of Fame Store on the south side of FedExField.
Taylor had a home in Miami, where he grew up, and he was reportedly engaged to be married. He is the son of Pedro "Pete" Taylor and Donna Junor.
Taylor was the Redskins' first-round draft pick in 2004. He was the fifth overall pick out of the University of Miami.
The press release the Redskins issued after drafting Taylor stated the following: "Touted as one of the most sought after players in this year's draft, Taylor brings a tremendous combination of size, speed and strength to the Redskins defense, as well as his well documented abilities as a playmaker and intimidator in the secondary."
Taylor lived up to that billing in four seasons with the Redskins.
As a rookie, Taylor played in 15 games, with 13 starts, and recorded 89 tackles, second-best on the team. He had one sack and four interceptions.
He finished fourth in NFL Defensive Rookie of the Year voting and was named a first alternate to the Pro Bowl.
Taylor earned his first and only Pro Bowl bid after the 2006 season in which he logged a team-high 129 tackles (89 solo), one interception and three forced fumbles.
This season, Taylor has played free safety opposite promising rookie LaRon Landry and led the team with five interceptions. He was sixth on the team in tackles with 46 (34 solo). He also had one forced fumble and eight passes defended.
For his career, Taylor has 344 tackles (245 solo), 12 interceptions, 41 passes defended and four forced fumbles.
