The former Manchester City goalkeeper's short-term contract at Tannadice is due to finish in January.
With Dusan Pernis signed, Weaver will be free to leave and he is hoping that his stint with United will have proved that he is over the injuries which have dogged his career.
"I still class myself as a decent age for a goalkeeper, I am 30 now and fully over my knee injury," he told Sky Sports News.
"It is just a case of waiting and if the phone rings then great.
"I wouldn't rule anything in and wouldn't rule anything out, a year ago I wouldn't have thought I would be playing in Scotland. I am fully open to all offers so it is just a matter of waiting and seeing what the future brings."
