The 25-year-old is due back at Dean Court when his three-month loan spell with AFC Wimbledon comes to an end after Saturday's home game against Rotherham.
Gregory, who helped Wimbledon secure promotion to the Football League before moving to Bournemouth 18 months ago, has made 17 appearances since rejoining the Dons in September.
"I knew that it would be good coming back here and I have enjoyed my three months at the club," he told the Dons' official website.
"I have not spoken to Bournemouth, but I will speak to them after Saturday about how we are going to move forward and what is best for both parties.
"Hopefully, by next week I will know what the situation is."
