Saddled with the NBA's worst record, the Atlanta Hawks on Monday activated forward Alan Henderson from the injured list.

Henderson, who has missed the entire season with a back injury, practiced with the Hawks (8-24) on Monday afternoon and will be in uniform for Tuesday's game against the Washington Wizards.

A nine-year veteran, Henderson has career averages of 6.8 points and 5.5 rebounds per game. Last season, he avoided major injuries for the first time in four seasons and was the only Hawk to play in all 82 games.

To make room for Henderson, the Hawks waived forward Lee Nailon, who averaged 5.3 points and 2.3 rebounds in 27 games this season.

Nailon was signed by Atlanta on September 30 after playing in just 38 games last season for the New York Knicks.
