Riccardo Ingram's football and baseball career at Georgia Tech ended yesterday when the senior admitted accepting money from sports agents and signing a representation contract in violation of NCAA rules.

Georgia Tech Athletic Director Homer Rice said the violations were reported to the NCAA, and Ingram was declared ineligible for the remaining football games against Wake Forest and Georgia, as well as for the 1988 baseball season.

In a statement, Ingram, a defensive back who has been the leading tackler for the Yellow Jackets this fall, said, "I'm very sorry for what I did. I know I've caused a great deal of embarrassment to Georgia Tech.

"I tried to say no, but they kept telling me that it would be good for me and good for them. When I gave in, I knew I was doing something that wasn't right. I felt guilty and scared."

The school did not reveal the names of the sports agents or the amount of money involved, but The Atlanta Constitution reported in a copyrighted story that Ingram received at least $4,000 from Jim Abernethy and Gary Wilson of Atlanta and signed a representation contract with them.

Ingram, who is from Douglas, Ga., had 79 tackles in eight games this season. He batted .426 with 17 home runs and 99 RBI last spring for Tech's Atlantic Coast Conference-champion baseball team . . .
