The NFL's controversial supplemental draft of Cris Carter and Charles Gladman, postponed for a week to give the athletes a chance to regain their college eligibility, is on again for today. No appeal was made in either case.

The draft, which college officials complained would encourage athletes to break the rules to turn pro, had been acceded to "reluctantly" by the league under threat of a lawsuit.

Carter, an all-America wide receiver from Ohio State, has admitted taking $5,000 in loans and another $1,800 later from sports agents Walters and Lloyd Bloom. Gladman, a Pitt running back, was declared ineligible for refusing to cooperate with an inquiry into the agents . . .

Soldier Field, the lakefront home of the Chicago Bears, will replace its artificial turf with natural grass in time for the 1988 NFL season, officials said.

The decision to remove the artificial turf honors a year-old request by Bears President Michael McCaskey, who apparently has fielded complaints from players about turf-related injuries . . .

Houston officials say they have done all they can to keep the Oilers from moving to Jacksonville, Fla., when the NFL team's lease at the Astrodome expires at the end of this season. The Oilers are being wooed by Jacksonville officials to make the Gator Bowl their home.

Jacksonville Mayor Tommy Hazouri said he thinks the north Florida city can deliver on its proposal of guaranteeing $115.2 million over the next 10 years for the NFL team. Oilers owner K.S. (Bud) Adams confirmed that he is asking for that sum.
