Concussion protocol for Giants' Dart under review

The NFL has initiated a review of the concussion protocol used in the evaluation of New York Giants rookie quarterback Jaxson Dart in the second half of the team's game against Philadelphia.

The league announced Friday the review will be conducted jointly with the NFL Players Association.

Cameras caught coach Brian Daboll poking his head into the blue injury tent on the sideline when Dart was being checked for a concussion Thursday night. Dart grabbed his head after taking a hit while being sacked by Patrick Johnson and falling into another Eagles linebacker, Azeez Ojulari, late in the third quarter.

Daboll was impatient about the time it was taking to clear Dart, saying he just wanted him out there "if he was OK." Former starter Russell Wilson, who was benched four games into the season, entered the game and threw an incomplete pass on his only attempt.

"I apologized directly to our team physician," Daboll said, acknowledging he was in the wrong. "We were getting ready to go for it on a potential fourth down. I would have burned a timeout if he could have come out there. I was asking how long was it going to take. You want your guy out there, not at risk of anything else."

The league's chief medical officer, Dr. Allen Sills, told reporters attending a pregame tour of MetLife Stadium medical facilities that there were specific rules about who could be in the tent during a concussion evaluation -- namely, the player, a team physician, an independent specialist and potentially a team athletic trainer.

"Never more than those people," Sills said. "Never any coaches in here, never any other players in here, never anybody else in here."

Giants rookie Cam Skattebo also poked his head into the tent, joking he was "making sure that Jaxson wasn't hurting anybody in the injury tent."

"I knew going over there I needed to calm down a little bit because I knew he was going to be on fire," Skattebo said. "When I was in there, he was a little fired up, but we know we have to go through protocol and do all that stuff to make sure we can get back on the field. I went in there and kind of, 'We're good, man, we've got you,' and that's it."

It's at least the third time, counting preseason, that Dart has missed some amount of time during a game because of a concussion evaluation, and he said he is tired of the interruptions.

"It felt so long," Dart said. "A few guys popped in. I was just trying to get back there on the field. I understand they have protocol and whatnot. I was just trying to get out there fast."
