A couple hard hits on Cowboys quarterback Dak Prescott weren’t flagged during last Sunday’s loss to the New York Jets.

They should have been.

Late in the first quarter, Jets defensive end Kyle Phillips jumped in the immediate vicinity of Prescott as a teammate pulled Prescott to the ground. Phillips appeared to catch Prescott’s head with his right quad on the way up before landing on Prescott’s head on the way down. In the second quarter, on a critical drive, linebacker Neville Hewitt left his feet and lowered his head to drive into Prescott’s midsection after a throw.

Two illegal hits. No penalties. This week, the NFL fined Phillips and Hewitt $21,056 each, a source said Saturday.

Prescott grabbed his head area immediately following Phillips’ second hit, prompting an independent certified athletic trainer to consider the play to be potentially concussion-inducing. The spotter mandated that Prescott undergo a concussion evaluation on the sideline. He passed and returned to action without missing any snaps. The drive ended with a 50-yard Brett Maher field goal.

Hewitt’s hit was especially egregious, and the missed call changed the complexion of a vital possession.

Like on the Phillips play, a 15-yard penalty for roughing the quarterback should have been assessed. Had it been, the Cowboys would’ve had first-and-10 at the Jets’ 25-yard line instead of the play’s result, which was first-and-10 at the 40. This drive ultimately stalled at New York’s 8-yard line following a failed fourth-down conversion. The Jets then connected on a 92-yard touchdown pass on the ensuing play. This was a key sequence to the 24-22 loss.

What’s done is done, although Hewitt is still feeling the effects. He suffered a stinger when spearing Prescott and is listed as doubtful to play this Monday against the New England Patriots.

On Thursday, Prescott said that an official apologized to him during the game for having missed Hewitt’s hit. Prescott’s stature at 6 feet, 2 inches and 235 pounds may help him deal with the physical contact -- “I am fine,” he said of his medical standing -- but he acknowledged it may not help the optics when officials are determining what is or isn’t a penalty.

“I’m guessing that just on the fact I don’t react as much,’’ Prescott said. “I get hit, and sure, I can absorb it. Or I’m strong enough that it doesn’t flip me or make me have this crazy response that I’m not getting up. Now I feel bad for griping and (complaining) when they call the fouls for (NBA star) LeBron (James). He has been getting fouled. He’s just strong."

Cowboys defensive tackle Maliek Collins horse-collar tackled Jets quarterback Sam Darnold during the first quarter. Collins was flagged 15 yards and fined $21,056, a source said.

Like Phillips and Hewitt should have been.
