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.

The Chicago Bears released veteran defensive lineman Jeremiah Ratliff and signed defensive lineman Ziggy Hood, the team announced Thursday.

"We felt moving forward without Jeremiah was in the best interest of our team," Bears general manager Ryan Pace said in a prepared statement. "We appreciate his contributions and wish him well."

Ratliff, dressed in Bears warm-up clothes, and Pace were observed having an animated conversation in front of Halas Hall around 11:30 a.m. CT while the rest of the team was on the practice field. The exact nature of Ratliff and Pace's conversation is unknown, though sources told the Chicago Tribune that team officials judged that Ratliff arrived not in a condition to work. Two team security guards stood only a couple of feet away during the conversation.

A squad car from an area police department was seen patrolling the Halas Hall grounds at approximately 3 p.m.

The NFL suspended Ratliff for the first three games of the regular season for violating the league's substance abuse policy.

The New Orleans Saints have released kicker Zach Hocker and will sign Kai Forbath.

Hocker missed a potential game-winning 30-yard field goal against the Cowboys and then missed a 51-yard and 48-yard attempt last week.

Hocker won the job over Dustin Hopkins in training camp, likely on the merits of his work in preseason games. 

The Pittsburgh Steelers have cut Josh Scobee and signed Chris Boswell.

Scobee missed two field goals in the final three minutes of the fourth quarter to set up the Steelers' loss in Week 4 to the Baltimore Ravens.

Scobee made just six of 10 field goal tries and missed one extra point in four games in Pittsburgh.
