5 momentous plays: Nick Sirianni's field-goal decision, plus Kamari Lassiter's painful penalties

Week 4 wasn't quite the closely contested affair that Week 3 was , but there still were several one-score games that were decided by a handful of key plays.

A few were bad luck. Some of the close games came down to a handful of plays. But there were some below-the-radar moments in several of the tight ones that shifted the tides.

Here are some of the bigger but less-than-obvious momentum shifters in Sunday's games:

1. Kamari Lassiter's nightmare drive haunts Texans

Midway through the third quarter, the Texans led the Cowboys 23-13, and had Dallas in a third-and-7 at the Houston 8-yard line. It appeared Houston got a stop, but Texans cornerback Kamari Lassiter — who allowed a 53-yard catch earlier on the drive — was flagged for a back-breaking pass interference call.

Houston held firm the next three plays, moving the Cowboys back two yards. But on fourth-and-goal from the 3-yard line, Lassiter again was flagged, this time for holding. Houston couldn't hold again, as Javonte Williams' TD cut the Texans' lead to three.

That series completely flipped the game, one Dallas stormed back to win in the final minute .

The Texans were actually on the right side of a few big momentum plays before and after this. They blocked a field-goal try near the end of the first half, kicking their own FG for a six-point swing in a 30-second span. They also converted a third-and-14 hook-and-ladder play for 21 yards, setting up Houston's go-ahead TD with 2:26 remaining in the game.

But not getting that goal-line stop potentially cost them four points … in a four-point loss.

Lassiter is a talented, young player, but he and the Texans are in a dark place right now at 0-4.

The most controversial momentum swing came when Eagles head coach Nick Sirianni opted to go for it on fourth-and-goal from the 2, instead of kicking a field goal, leading 20-10 with 7:26 remaining against the visiting Rams. Jalen Hurts' pass was incomplete, and the Eagles got zero points out of the drive.

Perhaps trying to go for the kill shot there wasn't the worst idea in an effort to make it a three-possession game. A field goal would have given the Eagles a 13-point lead, but the Rams scored two TDs after that stop, so that one play didn't tilt the game by itself.

But Tank Bigsby and Will Shipley — filling in for an injured Saquon Barkley — had been running effectively on the drive, grinding away at the Rams. Hurts also is one of the better short-yardage running QBs in the game, although the Rams had stuffed a tush push late in the third quarter, which surely had to factor into Sirianni's thinking. It also didn't help that Hurts' timing on the third-and-goal play was thrown off by Cam Jurgens pulling too quickly, resulting in a no-gain.

Whether or not Sirianni made the right call, it backfired. Matthew Stafford looked down and out after his previous five possessions came up empty, but this was the spark he and his offense needed.

The Rams drove 98 yards on their ensuing drive to keep the game alive, and after the Eagles' 64-second three-and-out, the Rams went down and scored again for the improbable win .

The Eagles are in rough injury shape, and they've now lost two straight. Monday's loss in Chicago was a laugher, but they had Sunday's game in good shape before the late collapse.

3. Key INT, review help Packers hold off Bucs

In the final minute of the first half, the Bucs and Packers were tied at 7-all. Six game minutes later, the Bucs were down 10. Losing the middle portion of the game cost them dearly.

Rookie QB Jalon Daniels, filling in for an injured Baker Mayfield, threw a first-quarter interception, yet he was holding his own. Then Daniels threw his second pick of the first half, with Packers linebacker Edgerrin Cooper diving to make the grab and running it back 18 yards into Bucs territory.

That set up a Trey Smack 58-yard field goal and a little bump for the Packers before halftime. On their first possession of the second half, Jordan Love hit Tucker Kraft for a touchdown. Initially, it was called incomplete but later overturned after replay — and it was hardly obvious whether Kraft's foot clearly hit before he secured the catch.

It was an ugly game. Cooper left with an Achilles injury. Kaleb Johnson fumbled inside the 5-yard line. Love had a chance to make it a 10-point lead with four minutes left, but he threw an interception. The Packers were 2 for 10 on third downs.

The Bucs made their share of mistakes, too. But misplaying the middle section of the game, rookie quarterback or not, put them in an even tougher spot to pull off the upset .

The Raiders couldn't keep their unbeaten streak going, falling to the Chiefs , but they made Kansas City earn that victory in Las Vegas. Had a few more plays gone the Raiders' way, who knows?

Dareke Young's fumble on a kickoff, trailing 23-19 with 3:21 left in the game, was the obvious late momentum shift — and, yes, it hurt badly, even if the Raiders had a chance to tie or take the lead on their final drive.

But there was an earlier shift that cost the Raiders three points that head coach Klint Kubiak might now be regretting.

Three minutes into the second half, the Raiders' Matt Gay hit a 41-yard field goal to temporarily put the Raiders up 16-10. But the Chiefs were flagged for illegal formation on the kick, and Kubiak opted to take the points off the board — in spite of it not giving them an automatic first down.

Kirk Cousins' fourth-and-2 pass to Ashton Jeanty fell incomplete. The score remained 13-10, and the Raiders ended up losing by three points.

Kubiak might also regret predicting the Raiders would win during his halftime interview. Not too long later, his field-goal decision hurt his team.

5. Bell's nullified touchdown sunk Dolphins

There has been talk about the possibility of the Dolphins going winless this season, but with a few more breaks, they might have been able to take down the Vikings in Minnesota.

The biggest play that went against them was a tremendous touchdown that evaporated into thin air almost as fast as it happened.

Early in the second quarter, Malik Willis scrambled and — off-balance and falling out of bounds — threw what appeared to be a 68-yard TD to talented rookie wide receiver Chris Bell on a third-and-4 play. For the briefest of moments, Miami was leading 3-0, and the U.S. Bank Stadium crowd was stunned.

But Bell was flagged for illegal touching, having stepped out of bounds on his own prior to the catch, which wiped out what would have been his first career touchdown. The penalty came with a loss of downs, forcing a punt. The Vikings went down and kicked the second of their five field goals on the day in a 15-10 win.

Miami finished the first half with only 76 yards on 21 plays. The Dolphins' offense got going a bit with a 10-point third quarter, but that's all the group could muster. The Bell touchdown would have changed the game dramatically.

The Dolphins scored the only touchdown in the game — and they should have had two — but the Vikings held on for victory. That's how much separated the winless Dolphins and the unbeaten Vikings playing in their home stadium.
