Chicago Bears -- Decided to move their practice sessions for the NFC playoffs to Suwanee, Ga., because University of Illinois officials have been unable to erect a plastic dome in Champaign that would have covered the field there, a team spokesman said. The Bears wanted to train at the university because club officials hoped to stay in a cold climate in preparation for freezing temperatures expected in Chicago when the Bears host their postseason opener, Jan. 5. Snow, low temperatures and high winds make outdoor practice in Chicago practically impossible this time of year. Cincinnati Bengals -- Said they plan no changes in their coaching staff for 1986. Assistant General Manager Mike Brown said the decision means Dick LeBeau will remain defensive coordinator under head coach Sam Wyche. The defense was strongly criticized as it gave up club-record 437 points in team's 7-9 season. New York Jets -- Activated CB Russell Carter; placed CB Bobby Jackson on injured reserve. BASKETBALL

Phoenix Suns -- Said G Jay Humphries has been fined $500 by the National Basketball Association for his part in a fight with Seattle SuperSonics G Gerald Henderson in a game Dec. 17 in Seattle. Henderson was fined $1,000. Boston Celtics -- Announced F Kevin McHale has been fined an undisclosed amount for failing to get to New York City on Christmas Eve. He flew to the city Wednesday, prior to that afternoon's double-overtime, 113-104 loss to the New York Knicks, in which he led Boston with 29 points. "It's no big deal," said McHale. "I missed the flight . . . I deserved the fine." HOCKEY

Toronto Maple Leafs -- Announced they have lost the services of C Greg Terrion for several weeks and G Ken Wreggett for at least seven days.
