- At 4pm ET on September 5, each team must reduce their rosters from 75 to 53 (assuming Hayne is selected in the 75-man squad named after this weekend's trial against Denver)

- Every player who hasn't been in the NFL for more than four years is subject to waivers. The waiver process is a 20-hour period where any team can put in a claim for a player who has been cut from an NFL team roster.

- If the 49ers want to keep Hayne on their additional 10-man practice squad, they have to hope no team adds Jarryd Hayne to their 53-man roster before midday on September 6.

- Waiver priority goes in the order of last year's draft, so the Tampa Bay Buccaneers would have first crack at Hayne, followed by the Tennessee Titans, Jacksonville Jaguars, Oakland Raiders, Washington Redskins and New York Jets.

- Hayne would leave under the current contract he has with the 49ers, which is a three-year deal worth $US1.58 million.

- If no team selects Hayne in the 20-hour waiver period, the 49ers have the chance to add him to their 10-man practice squad. However, Hayne is also free to take up offers from rival clubs who can pick him on their practice squad or active roster.

- If no team picks up Hayne, which seems highly unlikely, the future is in Hayne's hands.

IF JARRYD HAYNE MAKES THE 53-MAN ROSTER ON SEPTEMBER 5

- He isn't automatically guaranteed a position on the 49ers roster. The 49ers will have a look at players who were cut from other squads, and if they decide to bring in a new player Hayne may be squeezed out of the roster and forced to find a new home.

- If he maintains his position on the 53-man roster, the 49ers will select 46 active players for their first game of the season against the Minnesota Vikings at Levi's Stadium on September 14. If Hayne is one of the 46, he's likely to make his NFL debut on home soil against the Vikings.
