SANTA CLARA, Calif. (AP) Brock Purdy's storybook ride from final pick of the 2022 draft to most efficient quarterback in the NFL has featured very few on-field struggles.That's what made his in one of the most highly anticipated games of the season so glaring. How Purdy bounces back from the to the Baltimore Ravens on Monday night will go a long way in determining how succe sful this season will ultimately be for the 49ers.I think its unbelievable how Troy Brown Jersey hes played for the past two years," defensive end Nick Bosa said. "Just being a young rookie last year, it seems like hes immortal out there. But no one is immortal. Hes responded from not his best performance before and I think he will do that again.Purdy's night got off to a bad start when he didn't see safety Kyle Hamilton and threw an interception in the end zone on the first drive of the game for San Francisco (11-4).ADVERTISEMENT A deflected pa s off a cornerback blitz led to his second turnover and then a questionable decision to throw acro s his body over the middle on a play that already had a penalty on San Francisco led to the third interception.He was then hit on a pa s that was intercepted on the second drive of the third quarter, e sentially sealing San Francisco's fate. I just think the fact hes played this long and never had a game like this is pretty unusual, coach Kyle Shanahan said. I think thats the reality of the NFL. Im not saying its bound to happen, but I wish he didnt have as many picks. But like I said, I think one of them was one hed really liked to have back. The other three I think were unfortunate.It was by far the worst game of Purdy's 23 career Jerome Robinson Jersey starts in the regular season and playoffs. He had been on a near record-setting pace this season before the setback against one of the NFL's top defenses. But the lo s doesn't have to be crushing for San Francisco. The Niners can still clinch the No. 1 seed and a first-round bye with wins over Washington and the Rams the next two weeks.Its easy to be riding the high and thinking youre the man when things are going well, winning games and all that kind of stuff, and you dont really see a whole lot of adversity in some games, Purdy said. This is the reality of the NFL.WHATS WORKINGChristian McCaffrey. While there were plenty of struggles on Monday night, McCaffrey delivered once again. He rushed for 103 yards on 14 carries and added six catches for 28 yards. McCaffrey moved into a tie for the NFL lead with Raheem Mostert with his 21st touchdown and leads the NFL with 1,932 yards from scrimmage. McCaffrey set a franchise record with his eighth straight game with at Trevor Ariza Jersey least 100 yards from scrimmage. WHAT NEEDS HELPPenalties. San Francisco was penalized 10 times for 102 yards their second-most penalty yards in a game this season. Several of those infractions contributed directly to Baltimore scores. Safety Tashaun Gipson was called for a face mask and pa s interference on the Ravens' first TD drive, Ambry Thomas got called for holding on a field-goal drive later in the second quarter and punter Mitch Wishnowsky committed a late hit early in the third quarter to lead to a TD drive starting on the San Francisco 44. STOCK UPCB Jason Verrett. His play in his first game of the season wasn't great but getting back on the field was the main accomplishment. Verrett hadn't played a game since tearing his ACL in Week 1 of the 2021 season for San Francisco. He then mi sed all of last season with an Achilles tendon injury and has managed to play more than one game in a season only once since 2017 because of a long series of injuries. He played just five snaps on Monday and allowed a TD to Nelson Agholor.STOCK DOWNOffensive line. The Niners lost starters Trent Williams and Aaron Banks to injuries in the second half Troy Brown Jr. Jersey and struggled to protect Purdy. San Francisco allowed pre sures on 47% of drop-backs for Purdy and Sam Darnold, according to Pro Football Focus. Colton McKivitz allowed nine pre sures and Spencer Burford allowed four on 24 pa s block snaps after being forced to play tackle for the first time in his career. INJURIESShanahan had no update on the status of three offensive linemen who left the game with injuries: Williams (groin), Banks (toe) and T Jaylon Moore (concu sion). ... LB Oren Burks (knee), RB Elijah Mitchell (knee) and TE Ro s Dwelley (ankle) are expected to return to practice this week. ... The Raul Neto Jersey status of DT Arik Armstead (foot, knee) and WR Jauan Jennings (concu sion) remains in doubt this week.KEY NUMBER65.2 The big question hanging over Purdy is his ability to lead a team from behind. Purdy has struggled doing that season and that happened again on Monday night. Purdy is 37 for 63 for 554 yards, two TDs, five interceptions and a 65.2 pa ser rating when trailing in the second half. NEXT STEPSSan Francisco visits Washington on Sunday.___AP NFL:
