For the third time in quarterback Jalen Hurts’ past 30 regular-season starts, the Philadelphia Eagles lost on Sunday. For Hurts, the postgame approach to Philadelphia’s 42-19 loss to the San Francisco 49ers will be the same as for the 27 victories during that span.

“I think this is a moment where you go back and you reflect on it, you learn from it, like every win,” Hurts said. “You treat them all the same when you win and when you lose. It’s about: What can I learn from this? So the process remains the same in terms of how we respond and how we approach it. Just have to be self-critical, as we always are, and analyze everything as it’s supposed to be and respond. …

“It’s nothing changing in that process. It’s keeping the main thing the main thing. Staying true to that; staying true to who we are. And learning from it. Win, lose or draw, it’s always a deep, deep dive into what we can be better at, looking ourselves in the mirror and responding to the mistakes that we’ve made and also to the successes that we’ve had.

“And so it’s no difference here. It’s about how we respond and how bad we want to grow, how bad we want to better ourselves. And so that’s the mentality moving forward, and, obviously, that has to be done together.”

The Eagles trailed at halftime of their previous four games and came back to win each. And it looked as though Philadelphia was at it again when it went 58 yards in 10 plays on its first second-half possession. Hurts’ 1-yard touchdown plunge reduced San Francisco’s lead to 21-13 with 6:51 left in the third quarter.

But a couple of elements were missing on Sunday from Philadelphia’s other comebacks. The Eagles defense couldn’t stop the 49ers as San Francisco scored touchdowns on its final six full possessions of the game. And Philadelphia’s ground game never got going. Hurts ended up as the Eagles’ leading rusher with 20 yards on seven carries as Philadelphia totaled 46 rushing yards in the game.

Something else was missing in the second half for the Eagles – Hurts.

The former Alabama QB made a brief stop at the sideline medical tent, then headed for the locker room after being stopped for a 6-yard gain on a third-and-8 scramble with 2:32 left in the third quarter. The Eagles announced Hurts had gone to the locker room to be evaluated under the NFL’s concussion protocol.

When Philadelphia regained possession, Marcus Mariota was at quarterback. After five snaps, including a fourth-down conversion by the backup quarterback, Hurts was back in the game, and he completed a 13-play, 71-yard drive with a 2-yard touchdown pass to wide receiver DeVonta Smith to cut San Francisco’s lead to 35-19 with 5:33 to play.

“I thought he was fine when he came back in and was running the show and was operating fine,” Philadelphia coach Nick Sirianni said. “Went down and got a touchdown, and then we just stalled out on the next drive. …

“Obviously, we’ll see how he’s feeling and everything.”

Hurts said he returned to the game because he was “trying to keep fighting.”

“It was obviously an assessment in that moment,” Hurts said. “Everybody was doing their jobs and doing their roles. I was able to come back when everybody felt like I was ready to.”

For the game, Hurts completed 26-of-45 passes for 298 yards with one touchdown and no interceptions.

Philadelphia defeated San Francisco 31-7 in last season’s NFC Championship Game, and with Eagles at 10-2 and the 49ers at 9-3, the teams could be back there this season, too.

“Much credit to them and the way that they played today and how they executed,” Hurts said. “I think for us, we need to do a better job, a better job of controlling the things we can and playing cleaner. They played well and took advantage of their opportunities. That’s a really good football team.”

Hurts entered Sunday with a five-game winning streak as a starting quarterback in games in which Philadelphia trailed by at least 10 points. That was tied for the longest in the NFL since 1950, when the league began recording starts, with streaks by Joe Montana and Steve Bartkowski.

With Hurts as the starting quarterback, the Eagles had won their past 14 regular-season games against teams with winning records, giving the former Alabama QB the league’s longest such streak since 1950.

Although that streak ended, Philadelphia will face another winning team in its next game when the Eagles take on the Dallas Cowboys at 7:20 p.m. CST Dec. 10 at AT&T Stadium in Arlington, Texas.

Philadelphia defeated Dallas 28-23 on Nov. 5. But with a 9-3 record, the Cowboys would pull into a tie with the Eagles at the top of the NFC East with a victory next week.
