ATLANTA — Kirk Cousins has found his comfort zone in his new Atlanta Falcons offense.

That exciting realization came in the second quarter of Cousins’ record-setting 36-30 overtime win over Tampa Bay on Thursday night. Cousins said he felt more decisive in his passes to such targets as Drake London and Kyle Pitts and realized he could “let it rip.”

The more confident Cousins set a personal and team records by passing for 509 yards and finished with four touchdowns, including a game-winning 45-yard scoring pass to KhaDarel Hodge. The flurry of touchdowns was especially dramatic one week after Atlanta’s offense was held out of the end zone in a 26-24 win over New Orleans.

“It was a drive in the second quarter when I threw a couple passes where I was basically anticipating where Kyle was going to be or where Drake was going to be,” Cousins said of his new-found comfort zone.

“I was ahead of it a little bit in a good way and threw it decisively. I just haven’t been that decisive the first few weeks. I’ve been trying to ensure that’s where they’re going and ensure that’s what I’m seeing before I let it rip.”

Added Cousins of his ability to better anticipate receivers’ routes: “That’s what I was used to kind of having when you play with guys for three, four, five, six years. I can feel it starting to come.”

Falcons Coach Raheem Morris remained even-keeled when he described Cousins’ night as “OK” and added “We’re just scratching the surface with him.”

If so, that’s bad news for the NFC South after the Falcons (3-2) moved into a tie for first place in the division with the Buccaneers.

DOLPHINS: The NFL’s chief medical officer said Friday that the league won’t tell the Dolphins when Tua Tagovailoa can return to the field.

Allen Sills said the NFL won’t intervene in the decision on when Tagovailoa will return to the field after his Sept. 12 concussion against Buffalo, which was at least the fourth concussion in his life and possibly his fifth.

Tagovailoa has consulted “with top experts” around the country, Sills said.

The Dolphins have declined to say when Tagovailoa will return to the field because Coach Mike McDaniel has said speculation is counterproductive to Tagovailoa’s recovery.

BILLS: Buffalo is already missing suspended pass rusher Von Miller. Now, they will face the Texans on Sunday without leading receiver Khalil Shakir, Austin Johnson at defensive tackle and Taylor Rapp at safety.

The Bills (3-1) announced that Shakir, Johnson and Rapp would join Vonn on the sidelines when they face the Texans (3-1). Vonn was suspended four games for violating the NFL’s personal conduct policy.

The NFL, which announced the suspension Tuesday, did not give a reason for Miller’s penalty. Shakir, who has 18 catches for 230 yards and two touchdowns, is out with an ankle injury. Johnson is out with an oblique injury while Rapp is out with a concussion.

RAIDERS: Coach Antonio Pierce hasn’t ruled out defensive end Maxx Crosby, who missed his first career game last weekend, for Sunday’s game at Denver.

Crosby, who didn’t play in last Sunday’s 20-16 victory over the Cleveland Browns because of a high-ankle sprain, went through a limited practice.

There is an increasing chance running back Alexander Mattison will start against the Broncos. Usual starter Zamir White isn’t expected to play because of a groin injury.

GIANTS: Wide receiver Malik Nabers is still in the concussion protocol and is out for New York’s road game at the Seahawks on Sunday, Coach Brian Daboll said.

Nabers is progressing and getting better and doing some physical work with the trainers, Daboll said. But he was kept out of practice again on Friday for a third straight day and is not traveling with the team. Nabers, the No. 6 overall pick in the draft, has been the focal point of the offense. His 386 yards receiving are second in the NFL and he’s tied for third with three touchdown receptions.
