Jackson averaged 6.0 points, 3.0 rebounds and 1.0 assists in two preseason games. The cut leaves Chicago with 16 players.
Bell, a 6-foot-1 guard, played 10 minutes in the Hornets' 101-83 loss to Orlando on Saturday but did not score. He was 0-for-2 from the field and had one rebound, one assist and one turnover while committing three fouls.
The all-time scoring leader at Boston College, Bell signed as a free agent with the Hornets on Oct. 1. He was the first player cut from the Hornets during preseason camp. The Hornets, who will play 35 of their home games in Oklahoma City this season, now have 17 players on their roster.
The Celtics took Bell with the 16th overall pick in the 2003 NBA draft and traded him to Memphis, where he played six games. Tendonitis in his left knee caused him to miss most of that season, and the Grizzlies waived him prior to the start of last season.
The 6-foot-2 guard signed with the Lakers on Sept. 19 and participated in training camp in Hawaii, where he had four points and one assist in 20 minutes of the Lakers' 112-81 preseason loss to Golden State.
Conroy played four years for the University of Washington, averaging 9.2 points and 4.3 assists in 121 games. He averaged 4.4 points and 2.2 assists in seven games for the Lakers' team in the Summer Pro League.
