NFL-National Football League roundup

Oct 6 (The Sports Xchange) - Carolina Panthers quarterback Cam Newton was not on the field on Thursday morning as the team began practice. Newton and left tackle Michael Oher were absent as both remain in the league's concussion protocol. The pair has an extra day of healing as the Panthers (1-3) host the NFC South rival Tampa Bay Buccaneers (1-3) on Monday night (8:30 p.m. ET). - - New York Jets veteran cornerback Darrelle Revis and wide receiver Eric Decker remained spectators during practice. Revis has yet to practice this week after sustaining a mild hamstring strain during Sunday's 27-17 loss to the Seattle Seahawks. Decker is in jeopardy of missing his second straight game with a partially torn rotator cuff. - - Minnesota Vikings wide receiver Stefon Diggs sat out practice for the second straight day due to a groin injury. His status for Sunday's game against the Houston Texans is uncertain. Tight end Kyle Rudolph participated in practice after being bothered by a clavicle/rib injury sustained against the Giants. - - Running back Karlos Williams is expected to re-sign with the Buffalo Bills after serving his four-game suspension for violating the league's substance abuse policy. - - Green Bay Packers cornerback Sam Shields has been ruled out of Sunday's game against the New York Giants (2-2) due to the concussion he sustained in the season-opening win versus the Jacksonville Jaguars. - - Johnny Manziel, officially reinstated by the NFL after serving a four-game suspension, is a free agent eligible to be signed to a practice squad. Manziel became a free agent in March, but off-field antics and domestic violence charges in Texas kept interest lukewarm. - - San Francisco 49ers linebacker Aaron Lynch was removed from the roster-exemption list and activated, and linebacker NaVorro Bowman was placed on the injured reserve list, the team announced. - - The Dallas Cowboys worked out kickers Robbie Gould and Kai Forbath amid concerns about Dan Bailey dealing with a balky back, the NFL Network's Mike Garafolo reported. Bailey misfired on a 47-yard field goal attempt versus San Francisco last week, but rebounded to hit a 22-yarder and all of his extra points in a 24-17 win over the 49ers. - - Washington Redskins cornerback Josh Norman pantomiming firing a bow and arrow as part of a post-play celebration will cost him $10,000. Norman was flagged during a celebration after a fourth-quarter interception in a win over the Cleveland Browns. Norman did the same thing two weeks earlier against the Dallas Cowboys and received a warning from game officials. - - Pittsburgh Steelers wide receiver Antonio Brown told ESPN that he has been fined again for his touchdown celebration dance against the Kansas City Chiefs this past weekend. Brown was fined $9,115 for twerking in the opener, and a second offense in taunting would be $12,154. Each of those celebrations led to a 15-yard unsportsmanlike conduct penalty. - - The Atlanta Falcons will forfeit their first three days of Organized Team Activities in 2017 for excessive contact in offseason workouts. The penalty stems from Atlanta breaking rules prohibiting excessive contact in an offseason workout in May. The club allowed players to engage in excessive levels of on-field contact, which is prohibited under the NFL-NFLPA Collective Bargaining Agreement. - - The NFL is closely monitoring the weather situation as it pertains to Hurricane Matthew, particularly the Tennessee at Miami on Sunday and the Tampa Bay at Carolina game on Monday night. No schedule changes have been made yet. (Editing by Frank Pingue)
