The San Francisco 49ers have kept Jarryd Hayne for their 53-man roster.

Hayne was one of the biggest stars of the Australian rugby league.

Hayne might be on the roster because of his performance in Week 2 of the preseason -- he rushed for 54 yards on eight carries and returned three punts for 84 yards against the Dallas Cowboys.

Hayne's preseason total of 175 rushing yards on 25 carries was second in the NFL, behind the Detroit Lions' Zach Zenner. His 7.0 yards per carry led the league, and his 163 yards on 10 punt returns ranked third.
