A trade to the Edmonton Oilers, completed Tuesday night, could not go through until Heatley decided whether or not to waive his no-movement clause.
"No decision tonight," a source in Heatley's camp told ESPN.com at 12:06 a.m. ET.
So what now?
Senators GM Bryan Murray had said all along he wasn't interested in moving Heatley after having paid him the $4-million bonus that kicked in at midnight ET Wednesday night.
The New York Rangers had been rumored to be interested in Heatley but the Rangers chose to sign Marian Gaborik instead.
"I'm not going to get in what [Ottawa] was asking for," Rangers general manager Glen Sather said in a conference call held to announce Gaborik's signing.
"But, when we signed Gaborik we were happy to get him. We didn't have to give up anybody out of our lineup. The money is the same. The term is the same."
Heatley met with Edmonton Oilers president Kevin Lowe and GM Steve Tambellini in his off-season home of Kelowna, B.C., earlier Wednesday night but the sales pitch didn't produce the immediate result.
