Delisted Cory Gregson hasn't given up hope of resurrecting his 39-game AFL career.
"A couple have rang Tim, my manager, and I think maybe one or two have called Wellsy as well," Gregson said.
"It's positive signs at the moment, but it's still very early."
He had surgery in July to insert a screw into his navicular bone to deal with a stress fracture, and has returned to running with the assistance of an anti-gravity machine.
Gregson said he had problems after his first couple of surgeries due to having the wrong screws inserted into the bone.
"The first two for mine were just the wrong screws put in my navicular," he said.
"They were a tad too big, which caused the bone to crack again and needed to have the next two surgeries."
