Douglas is expected to make the announcement on Tuesday, however, he is not expected to retain an agent, which would make him eligible to return to Auburn for his sophomore season.
An Auburn basketball source said that Douglas is "testing the waters" and he is not expected to leave. It appears unlikely that he would be drafted by an NBA team, which only has two rounds in its annual talent selection which includes college players, high school seniors and players from other countries.
The six-foot-one guard averaged 16.9 points, 5.3 rebounds, 1.8 assists and 1.4 steals per game. He shot 42 percent from the floor, 37 percent from three-point range and 79 percent at the foul line.
Douglas, who is from Jonesboro, Ga., was named to the All-SEC Freshman team and was a third team All-SEC pick.
A total of 60 players are selected in the two rounds of the NBA draft.
Douglas is just the fifth Auburn underclassmen to declare himself eligible for the draft. That group includes forward Charles Barkley (1984), forward Mike Jones (1988), guard Jamison Brewer (2001) and forward Marco Killingsworth, who withdrew his name from consideration in 2004.
