With Green Bay Packers starting receiver Davante Adams doubtful to play Sunday, more opportunities could be coming rookie Ty Montgomery's way.

He is proving worthy of more looks after only three games in the NFL.

"Ty's doing well, man," receiver James Jones said Friday before the unbeaten Packers (3-0) left for their Sunday game at San Francisco.

Montgomery has been contributing on offense, filling a void at a position depleted by the loss of playmaker Jordy Nelson to a season-ending knee injury in the preseason and, most recently, a nagging ankle injury for Adams.

A third-round pick out of Stanford, Montgomery has excelled as Green Bay's kickoff returner, ranking among the league leaders with an average of 31.5 yards.

The Packers may have to depend on Montgomery in an increased dual role Sunday. Adams was downgraded from questionable to doubtful on Saturday.

It's believed Montgomery will be ready.

"I think the main thing with Ty is he just puts in a lot of film study," Jones said. "He asks a lot of questions, whether it's to the quarterbacks, whether it's to the coaches, whether it's to us [the receivers]. He asks a lot of questions, studies a lot of film, and he wants to get better."

The Packers also promoted Jared Abbrederis from the practice squad to the active roster to bolster receiving depth.

Steelers cut kicker

Josh Scobee's miserable fourth quarter against the Baltimore Ravens cost him his job.

The Steelers cut the veteran kicker on Saturday, less than 48 hours after a pair of late missed field goals by Scobee helped the Ravens rally for a 23-20 overtime victory.

The Steelers traded away a sixth-round draft choice for Scobee before the season began and are on the hook for his salary for the remainder of the season, but they are moving on to their fourth kicker this season because he missed four of his 10 attempts and also missed an extra point.

Pittsburgh replaced Scobee on the roster with Chris Boswell, who has spent time with the Houston Texans and New York Giants but has never kicked in a regular-season game.

Lions wait on LB Levy

DeAndre Levy almost certainly will have to wait another week to make his season debut, but the Detroit Lions linebacker said he took "a big step" in his return from a strained hip muscle this week just by getting on the practice field.

"This week, it was big progress," Levy said after practice Saturday. "But it's kind of just a test, test, test and respond before I can go and play 60, 70 snaps in a game."

The Lions listed Levy, their leading tacker last season, as doubtful on their official injury report, meaning he has just a 25 percent chance of playing Monday night against the Seattle Seahawks.

Etc.

• Detroit running back Joique Bell was ruled out of the Lions' game Monday night at Seattle because of an ankle injury.

•The New York Giants signed tight end Will Tye off their practice squad, a move necessitated by injuries. Two other tight ends, Daniel Fells and Jerome Cunningham, did not travel with the team to Buffalo because of injuries.

•The Chicago Bears signed punter Spencer Lanning and waived defensive tackle Brandon Dunn. Usual punter Pat O'Donnell has a right knee injury and is questionable for the Bears' home game Sunday against Oakland.

•The Baltimore Ravens obtained wide receiver Chris Givens from the St. Louis Rams for a conditional draft pick. Baltimore needed help at the position because of injuries. Now in his fourth NFL season, Givens has 88 catches for 1,433 yards and four touchdowns in his career.
