San Francisco 49ers linebacker Fred Warner hailed the team for standing tall on the road after they held off a Seattle Seahawks fightback for a crucial 36-24 win.

The Niners were in dire need of a victory after blowing double-digit fourth-quarter leads in losses to the Los Angeles Rams and Arizona Cardinals in Weeks 3 and 5.

They made a strong start to Thursday's meeting between two NFC West rivals, assuming a 23-3 lead early in the third quarter, as Brock Purdy threw a 76-yard catch-and-run touchdown to Deebo Samuel and another score to George Kittle.

However, the defending NFC champions let Seattle back in and saw their lead trimmed to six points by the start of the fourth, with the Seahawks reeling off 14 straight points then getting the ball back via a Rasheem Green interception.

However, they held firm and another two touchdowns – a second Purdy-Kittle link-up and a six-yard Kyle Juszczyk rush – ensured they improved to 3-3, level with Seattle. 

Asked if doubts began to creep in as the Niners' lead shrunk, three-time All-Pro Warner said: "A thousand percent. 

"It sucks, but yes, it was something that felt familiar for sure. We could go one of two ways right there. 

"We could stand tall in a hostile environment and get the game that we got to get or we could settle for exactly how we've been playing the last couple losses."

The 49ers' season has seen them hampered by injuries to the likes of Christian McCaffrey, Dre Greenlaw and Javon Hargrave, and head coach Kyle Shanahan was handed another headache on Thursday as running back Jordan Mason was forced off with a shoulder issue.

Asked for an update on Mason's condition after the game, Shanahan said: "He thought he was going to be alright.

"He went back in, and it just hurt him too much, so he went out. We'll find out more tomorrow."

San Francisco's victory came at a crucial time as they are involved in the matchup of the season so far in Week 7, when they face the Kansas City Chiefs in a repeat of February's Super Bowl LVIII clash.

Offensive tackle Trent Williams said of that game: "It's not like we can get payback for losing in the Super Bowl. That ship has sailed. 

"Obviously, we know what type of team that is, one of the best teams in the league... All-Star quarterback, great coach. 

"We're going to take these three days off and regroup and try to put a complete game together."

San Francisco 49ers receiver Brandon Aiyuk is currently in a contract battle with the team, and Fred Warner believes it is a "good issue to have".

Aiyuk was in contract negotiations with the 49ers to extend his current deal but reportedly has not held talks with them since May.

Unable to reach a deal, the 26-year-old instead asked for a trade.

It is not the first time the 49ers have found themselves in lengthy contract disputes, going through the same process to resign Nick Bosa, Deebo Samuels and Warner himself.

The linebacker was unfazed by the controversies though, instead choosing to focus on the positives.

"When you're part of such a talented roster, I feel like this is something that goes on every season," Warner said via NBC Sports Bay Area.

"It's a good issue to have because, obviously, that means that your players are performing at such a high level that you have to have these kinds of conversations."

Aiyuk is under contract with San Francisco for 2024 in the option year of his rookie deal.

He impressed last season on their run to Super Bowl LVIII, earning second-team All-Pro honours and ranking seventh in the NFL with a career-high 1,342 receiving yards.

His average of 17.9 yards per catch ranked second in the league, while only the Miami Dolphins' Tyreek Hill bettered his 16 receptions of 25 or more yards.

Overall, since being picked in the 2020 draft, Aiyuk has 269 receptions for 3,931 yards, with 25 touchdown catches in 62 games.

As a key figure in the team, Aiyuk has been supported by his team-mates throughout the dispute, and Warner said he is ready to welcome him back when the saga is sorted.

"It's a part of the business, and so we all just let them handle that. And when he's back, he's back. We'll welcome him with open arms."
