The former Rugby League star made a lasting impression on Saturday night with his frisky work out of the Niners backfield.
"I saw him hit the hole and just go," said backup quarterback Blaine Gabbert of Hayne's big run, per The Mercury News. "The O-line did a tremendous job getting all the reaches. (Fullback) Bruce (Miller) threw somebody out of the park, opened up a giant hole for Jarryd, (who) made the safety miss in open space and he almost broke it."
Hayne told the newspaper he "felt a huge weight lifted" after playing his first game in an NFL uniform, saying: "I put a lot of pressure on myself. I wanted to go out there and fit in. I didn't want to go out there and look like a rugby player. I wanted to look like an American NFL player and I felt I did that."
Tight end Garrett Celek called Hayne a "beast," adding: "For as much improvement as he's made since (spring workouts), it's incredible. He's going to keep getting better and better."
Quarterback Colin Kaepernick called the 6-foot-2 Hayne's growth "amazing," while coach Jim Tomsula called him a "premier athlete in the world in space."
Tomsula acknowledged that Hayne "absolutely has to battle" to make the team, but with another repeat of Friday's production, this Australian-Rugby-League-star-turned-NFL-running-back has a chance to make good on Bush's April prediction.
