MELBOURNE, Australia — For the second straight season, the San Francisco 49ers beat the Los Angeles Rams on the road thanks to a critical goal-line stand.

A year ago, it was defensive tackle Alfred Collins knocking the ball from Kyren Williams’ grip before the running back crossed into the end zone. On Thursday, it was a team effort that prevented Matthew Stafford from crossing the goal line and cutting San Francisco’s lead to three.

The 49ers held onto the ball longer than the Rams — 33:50 vs. 26:10 — and committed fewer penalties, two to four. Only six infractions? Perhaps that’s why the game wrapped up in a tidy 2 hours and 47 minutes.

The 49ers offense was on the field for 65 plays, the defense for 61. Here’s how the individual snaps were doled out:

Quarterback: Brock Purdy 65

Purdy’s most remarkable statistic might have been his average depth of target (ADOT), which was only 4.9 yards. His average is usually double that number. The reason was the flurry of screen plays San Francisco ran, likely called to slow down edge rushers Myles Garrett and Byron Young. Purdy attempted 11 screens and completed 10 for 40 yards. By contrast, the 49ers attempted one screen in their previous meeting with the Rams in Week 10 last season.

Running back: Christian McCaffrey 36, Kyle Juszczyk (fullback) 33, Kaelon Black 28, Deebo Samuel 2

Black’s 65 rushing yards stood out for a team that’s been loath to give rookie runners many opportunities. However, it wasn’t the most for a Week 1 rookie under Kyle Shanahan. In the 2021 opener, then-rookie Elijah Mitchell finished with 104 yards in a win at Detroit.

McCaffrey, who averaged just 3.9 yards a carry last season, averaged 6.8 per run against the Rams. That included runs of 14 and 16 yards in the second half.

Wide receiver: Mike Evans 49, Demarcus Robinson 41, Samuel 25, De’Zhaun Stribling 21, Jacob Cowing 5, KhaDarel Hodge 1

Evans’ first three catches came on third downs when he was lined up out of the slot and all were converted into first downs. Evans and Stribling started the game at wideout.

Stribling and linebacker Jaden Dugger were the only rookie starters, although Black, offensive lineman Carver Willis, and defensive linemen Romello Height, Gracen Halton and James Thompson also got into the game.

Tight end: Luke Farrell 46, George Kittle 30, Jake Tonges 8

Kittle’s return to the lineup following his January Achilles tear was one of the big stories leading up to the game. But blocking specialist Farrell ended up with more receiving yards — 19 to Kittle’s 12 — including a critical 14-yarder when the 49ers were backed up against their own goal line.

“It was clutch for Luke to have that catch and getting us out of there,” Purdy said.

Shanahan said Tonges’ knee injury, which occurred in the second quarter, “wasn’t good.”

“It’s not an ACL, it’s an MCL, I believe,” Shanahan said. “But there are some issues with it; we got to see how it is.”

If Tonges misses some time, the 49ers likely will bring Brayden Willis back to the active roster from the practice squad. Another option is rookie practice squad tight end, Khalil Dinkins.

Offensive line: Trent Williams 65, Connor Colby 65, Jake Brendel 65, Dominick Puni 65, Colton McKivitz 65

There was speculation before the game that Colby might rotate at left guard with Carver Willis. Instead, Willis played six snaps of special teams. Colby held up well in pass protection, surrendering one quarterback hit and one quarterback hurry.

Thanks in part to the quick passing game, the 49ers surrendered no sacks and allowed just eight quarterback pressures.

Defensive line: Osa Odighizuwa 36, Nick Bosa 36, Halton 31, Height 30, Keion White 30, CJ West 23, Thompson 21, Khalid Kareem 19, Ogbo Okoronkwo 18

West opened his second season starting the game at defensive tackle next to Odighizuwa. But Halton, the fourth-round rookie, outsnapped him 31 to 23. Halton and Odighizuwa were the defensive tackles on the pivotal fourth-down goal-line stand in the third quarter. Odighizuwa was credited for the tackle, though it seemed to be a group effort.

Linebacker: Fred Warner 53, Dre Greenlaw 40, Dugger 34, Garret Wallow 13

Warner’s 11 tackles give him 958 for his career, surpassing Patrick Willis for the most in franchise history.

The 49ers used a five-man defensive line 12 times against the Rams, all of them with Dugger — a 6-5, 242-pound linebacker — serving as the fifth lineman.

Tatum Bethune was inactive for the game, likely because Wallow is a better special teamer. Wallow entered as the team’s middle linebacker when the outcome was out of reach.

Cornerback: Deommodore Lenoir 61, Renardo Green 61, Upton Stout 36, Jack Jones 8

Green, battling a hamstring strain in the run-up to the game, made a crucial interception in the second quarter and drew praise from Shanahan after the game. Green had a down year last season. He finished with no interceptions and famously got dressed down by Shanahan on the sideline during a playoff loss in Seattle.

“He had such a good training camp phase one and OTAs,” Shanahan said Thursday. “He was one of the guys I was most excited about this year just in terms of taking such a big step from the year before, and he had that hamstring which set him back and he wasn’t able to go until this week. He was working all week to get up, and for him to be healthy enough to play through that game, make it through the game without getting an injury and to play at the level he did, I thought was huge.”

Safety: Marques Sigle 61, Ji’Ayir Brown 55, Malik Mustapha 6

Sigle had a strong outing, finishing second to Warner with nine tackles, including a couple in which he flew in from the secondary to cut down a Rams ball carrier just as he was getting up to speed. Brown, however, misjudged a 41-yard pass to Puka Nacua, which set up the Rams’ lone touchdown and was the longest play of the game. Brown finished with two missed tackles.

Special teams: Farrell 18, Wallow 13, Luke Gifford 13, Siran Neal 13, Ashtyn Davis 13, Hodge 12, Dugger 12, Eddy Piñeiro 12, Mustapha 10, Jon Weeks 8, Corliss Waitman 8, Sigle 8, Brown 7, Willis 6, McKivitz 6, Colby 6, Puni 6, Jarrett Patterson 6, Vederian Lowe 6, Juszczyk 6, Jacob Cowing 5, Tonges 4, Height 3, Samuel 2, Lenoir 2, Warner 2, Jones 2, White 2, Odighizuwa 2, West 1, Greenlaw 1, Halton 1, Bosa 1, Okoronkwo 1, Green 1, Stout 1

The 49ers elevated Hodge from the practice squad for the game because he’s one of the team’s top special teamers. He and Neal served as the gunners on punt coverage.

Mustapha and Davis had big hits on a day in which the 49ers’ coverage units outshone the Rams’. Los Angeles averaged 23.8 yards per kick return; the 49ers averaged 37.

Pineiro’s miss from 52 yards — the ball hit the right upright — is just his second field-goal miss as a 49er. A 64-yard attempt in Indianapolis last year went off the crossbar.
