The San Francisco 49ers have waived Jarryd Hayne in order to promote Kendall Gaskins to their 53-man roster.

Carlos Hyde has been ruled out with a stress fracture in his left foot.

Reggie Bush, rookie Mike Davis and Gaskins are the only healthy running backs who remain with the 49ers. 

San Francisco hopes Hayne clears waivers and they can re-sign him to their practice squad on Monday.
