The Washington Wizards exercised the fourth-year contract options on four players, including John Wall, the team announced Friday.

As per team policy, the financial terms of the deals were not released.

Wall, who was the first overall pick in the 2010 NBA Draft, averaged 16.3 points and 8.0 assists per game for Washington last season, but is expected to miss the first few weeks of the upcoming season with a stress injury to his left patella.

The former Kentucky standout also became the sixth fastest player in NBA history to post 2,000 points and 1,000 assists, doing so in 124 games.

Washington also extended Trevor Booker, Kevin Seraphin and Jordan Crawford through the 2013-14 season.

Booker, who was dealt to the Wizards in a draft night trade in 2010, posted career-highs with 8.4 points and 6.5 rebounds over 50 games last season.

Seraphin was acquired in a trade with the Chicago Bulls in 2010. He averaged 7.9 points per game for Washington in 2011-12.

Crawford appeared in 64 games last season and averaged a career-high 14.7 points per game. Crawford was originally selected by the then-New Jersey Nets in 2010 before he was dealt to Atlanta. The Hawks then sent the Xavier product to Washington in 2010.

The Wizards also exercised the third-year options on forward Jan Vesely and Chris Singleton.

Vesely, who was selected with the sixth overall pick in the 2011 NBA Draft, appeared in 57 games -- 20 starts -- for the Wizards last season and posted averages of 4.7 points and 4.4 rebounds per game.

Singleton was taken with the 18th overall pick in 2011. The Florida State product appeared in all 66 games for Washington last season and averaged 4.6 points and 3.5 rebounds per game.
