Throughout the year Tomsula has offered mixed reviews on the rugby league convert, including axing Hayne on October 31 before signing him to their practice squad two days later.
The fact he's on the 53-man roster for the final game gives the 49ers the Australian's rights for next year.
"That would've been great if I would've taken it to the house, but I got cut short there", Hayne said.
The 27-year-old Aussie's position in the team was a hot topic during coach Jim Tomsula's press briefing this week and was again discussed during offensive co-ordinator Geep Chryst's media opportunity on Friday morning AEDT. "He doesn't back away or have to ease into the game; he's excited to be out there making plays". Chryst pointed to a pass route he broke off too early against the Lions.
Hayne admitted his coaches have talked to him this week about some of the mistakes he made against the Lions, including being too excited and running routes too quickly.
It is in a game situation where Hayne still sometimes lacks the instinctual moves that other running backs who played the game since childhood have. "There were definitely a lot of highlights and a lot of things I can look back on and try to get better". "It would have opened my area of the field better and created more space to run through".
All five of Hayne's receptions (for 20 yards) came in the fourth quarter. He averaged 9.5 yards on eight returns, and he fumbled three times.
"I think he can run, I think he's big, I think he is hard to block, I think as he works on fielding punts he's going to be a really exciting player to watch moving forward and we really like him".
Hayne, proving his popularity with 49ers' faithful, was selected by the team this week for their "Meet the Niners" question and answer Twitter session with fans.
Shaun Draughn (knee) was placed on injured reserve Wednesday, the San Francisco 49ers ' official site reports.
"My body feels well", Hayne said. On the weekend, I got in a head-on contact, so the next day my neck was really sore. Then he'll jump on a plane for home, catch up with family and friends, relax by the ocean and set a training schedule created to get him ready for a second season with the 49ers. "I've definitely felt the physical side of it on the weekends, but it is what it is".
His homeland s strong coffee was the first thing he said he missed upon arriving at the 49ers offseason program in April.
"I could be in the hospital overdosing on caffeine", Hayne said, smiling.
The Sydney-raised San Francisco 49ers' running back in recent weeks has been growing a hipster beard, which might be in vogue with many American sports stars, but not with his beloved Nan.
