CHARLOTTE, N.C. — Derek Anderson is preparing as if he will start at quarterback for the Panthers against the Bucs in the game scheduled for Monday night as Cam Newton continues in the league's concussion protocol.
Anderson took reps with the first-team offense for the second straight day Thursday while Newton was absent from the outdoor practice.
Coach Ron Rivera had no update on Newton's status, saying he wouldn't make a decision on the league's 2015 MVP until later this week.
Newton was one of six starters who didn't practice, including running back Jonathan Stewart (hamstring). Six other starters, including wide receiver Ted Ginn, were limited as the injuries continue to mount for the 1-3 Panthers.
Anderson, 33, is 20-25 as an NFL starter but 2-0 since joining the Panthers six years ago. Both of those wins came against the Bucs in 2014.
"If I do end up playing, I want to prepare and not let my teammates down," Anderson said. "We can turn this thing around."
Cardinals 33, 49ers 21: Drew Stanton passed for two touchdowns to Larry Fitzgerald in his first start in two years, David Johnson rushed for 157 yards and two scores, and the visiting Cardinals capped their night with a safety on their seventh sack of San Francisco's Blaine Gabbert. The Cardinals, with quarterback Carson Palmer out hurt, got 17 points off three 49ers turnovers — two Gabbert interceptions and a fumbled kickoff return by Chris Davis — and had one drive extended by a running-into-the-kicker penalty.
FINES roundup: Three Bills defensive backs were fined for a pregame onfield altercation with members of the Patriots on Sunday. Safety Robert Blanton said the NFL fined him $21,000. Cornerback Nickell Robey-Coleman said he was fined $10,000. Safety Aaron Williams said he was fined but not how much. It was unclear whether any Patriots were fined; the NFL releases fine information each Friday. Several punches were thrown during a shoving match between players and coaches about an hour before kickoff.
• Steelers receiver Antonio Brown was fined $24,309 for his touchdown-celebration dance against the Chiefs on Sunday night, ESPN reported. The NFL has a rule against "sexually suggestive" behavior on the field. The Steelers confirmed the fine but not the amount. He was fined $12,154 for twerking in Week 1.
• The Falcons were penalized by the league for having excessive contact in offseason workouts. They must forfeit their first three days of organized team activities next year.
