The Niners stayed perfect on Sunday, and the play that set the tone might be the strangest of the NFL season so far. On just the second play of the game, facing third-and-12 from their own 18-yard line, Brock Purdy hit Mike Evans on a short pass, and Evans flipped the ball to Deebo Samuel on a hook-and-lateral. Samuel took it down the left sideline for the 80-yard lateral touchdown that opened a 36-30 win over the Arizona Cardinals at Levi's Stadium. The win moved San Francisco to 3-0.

The trick play nobody saw coming

Head coach Kyle Shanahan dialed up the call with the offense backed up, and Arizona never sorted out who had the ball. Evans was wrapped up near the line of scrimmage before he pitched it, and by the time the Cardinals reacted, Samuel had a lane. He beat All-Pro safety Budda Baker down the boundary and finished the lateral touchdown with room to spare.

The box score from the play reads like a typo. Samuel did not catch a pass or draw a target all afternoon, yet the lateral touchdown left him with the most receiving yards without a catch in NFL history, breaking a mark of 65 yards that had stood for more than six decades, according to a box-score breakdown from Niners Wire.

Samuel told reporters after the game that the team had walked through the play only once all week. He decided to go when he saw two defenders on Evans, and he was not about to slow down when Baker came at him. He added that he showed off the kind of speed he believes people underestimate.

Purdy stayed in control all afternoon

Brock Purdy finished 15 of 27 for 297 yards and four touchdowns, according to Reuters. The lateral touchdown counted as one of Purdy's four touchdown passes. His second scoring pass of the afternoon, a 23-yard strike to Evans, made it 14-0 early in the second quarter, and San Francisco kept the lead the rest of the way.

George Kittle caught two of those touchdowns, including a wide-open play-action grab that put the Niners back up by nine with 1:31 to go. Christian McCaffrey added a short touchdown plunge, and the Niners outgained Arizona by a wide margin despite holding the ball for barely 21 minutes.

Evans paid a price for the afternoon. He left before halftime with a rib injury and was carted to the locker room after his third catch, according to Cards Wire. He had entered the game questionable with a hip issue, and left tackle Trent Williams also exited with a stinger. The officiating held up on the lateral touchdown without controversy, which is its own small story in a season when the league's trust problem with officials has become a storyline of its own.

Arizona's rally came up one drive short

The Cardinals refused to fold. Jacoby Brissett completed 38 of 52 passes for 280 yards and two touchdowns, and the offense kept finding ways back into it. But Arizona stalled where it mattered most.

The Cardinals were flagged ten times for 86 yards and settled for field goals on two of five trips inside the red zone. Chad Ryland converted from 26 and 41 yards, while Eddy Pineiro answered with a 57-yarder as the first half expired. Ryland's 49-yard field goal with 34 seconds left cut it to six and set up the onside kick, which Samuel recovered to end the game. By then the lateral touchdown felt like ancient history.

It was the third straight week Arizona allowed an opening-drive score, and the lateral touchdown was the third such strike in three weeks, according to Cards Wire. The loss dropped the Cardinals to 1-2.

Why the play will live on

The hook-and-lateral has a long history as a desperation call. Shanahan used it on the second play of the game as a planned strike, and this lateral touchdown caught Arizona flat-footed because the defense was playing the catch, not the pitch. It gave the 49ers a lead that survived a shaky fourth quarter.

The win kept San Francisco unbeaten and alone atop the NFC West. Samuel now owns one of the strangest lines in the record book: a touchdown scorer with no catches and no targets, and the lateral touchdown that opened the scoring. In a weekend crowded with screens, Twitch's record watch quarter shows where the rest of the sports audience's attention is going.
