"I'm probably leaning toward leaving, but I'll know for sure in the morning," Jones said.
Thursday is the deadline for underclassmen to declare their eligibility for the draft, and Jones said he will have an official announcement then.
Jones said in November that he had submitted his paperwork to the NFL review committee for underclassmen, but said at the time it was strictly for informational purposes. He declined to discuss what he learned from the committee Wednesday.
Jones said that Allen's surprise decision Tuesday to forego his final year of eligibility to enter the draft did not play into his reversal on remaining at Georgia.
"Not really," Jones said. "I'm making my own decision and just doing what's best for me and my family."
Jones finished second on the team in 2008 with 76 tackles and was the only member of the Georgia secondary to record an interception. He finished with five picks for the season, including one in what appears to be his final game in the Capital One Bowl.
