IMO the 9ers need to adopt the George Costanza theory for the last 2 games.
Do the complete opposite to what they would normally do this season.
That means that have to play Hayne.
You know it makes sense.
And risk him having some good games then losing him in free agency.
Honestly the lack of knowledge in this thread is hilarious. The 49ers can't promote him, or they risk losing him.
I suggest some people who are saying they are idiots look at how the whole practice squad, waivers system works in the NFL. Hayne is no chance of getting promoted this season (maybe the last game, but for what purpose?), what they have done is very deliberate and they intend on signing him to a futures contract (or practice squad) for next season.
If Hayne were to be made 'active' this week, he would be ineligible under NFL rules to ever be in the practice squad again (too many weeks in the squad and potentially too many weeks active on game day). What does that mean? He hits free agency, can sign a futures contract but cannot train with the squad. It also gives other teams a peak into his development and gives them the option to sign him.
So the 49ers have a lot to lose by promoting him, and nothing to gain.
He wasn't even good in the games he played anyway. He has a long way to go before he's a bona fide NFL player, and being active on gameday isn't necessarily the best path to get there.
