The Jamaica striker is still recovering from the fractured leg he suffered in an ugly car crash before Christmas.
Antonio has returned to light training, though is off contract at the end of the season.
"When we have something to announce, we will announce it," Potter said when asked about Antonio's future on Friday.
"It's a unique situation with Michail in terms of how he's recovering from his injury, he's doing fantastically well, he's going through a lot, we'll support him and that's the main thing at the moment."
Four stalwarts to depart
Meanwhile, it was announced this week that Lukasz Fabianski, Aaron Cresswell, Vladimir Coufal and Danny Ings would all be leaving the club when their contracts expire this summer.
"Aaron, Lukasz, Vladimir and Danny have been a pleasure to work with in my time here so far," Potter added.
"They are all brilliant professionals on and off the pitch, with fantastic experience in the Premier League, and clearly loved and admired by their team-mates and everyone here at the club.
"We felt it was important to confirm this news now, out of respect for them and the service they have given to the club, and to allow our supporters to show their appreciation at our final home match of the season."
