Jarryd Hayne is set to end months of speculation when he announces his deal with a NFL club on Tuesday afternoon.

The 27-year-old, who quit the NRL in October to pursue an NFL career, has pencilled in a news conference in Sydney for Tuesday afternoon to announce a contract with either the Detroit Lions, San Francisco 49ers or Seattle Seahawks.

Hayne's management is still waiting on last-minute paperwork from the clubs before choosing which franchise the former Parramatta Eels fullback will join, but it is hoped it will arrive within the next 24 hours.

The news conference, which was initially hoped to have been held on Friday, is expected to be Hayne's last public appearance in Australia before he flies to the United States next week to continue individual training, probably in California.
