As the San Francisco 49ers prepare for their Week 2 matchup against the Miami Dolphins on September 19, 2026, the team finds itself grappling with uncertainty at key positions. Kickoff is set for 1:05 PM ET at Levi's Stadium, but the 49ers may be without their starting kicker, Eddy Piñeiro, who is listed as questionable with an undisclosed injury. Head coach Kyle Shanahan addressed the media on Saturday, revealing that the team will bring in a temporary replacement, with two candidates under consideration. "There’s two guys we’re deciding on, but not sure which one," Shanahan said. Piñeiro, known for his powerful leg and clutch performances, has been one of the league's most reliable kickers, but his potential absence could force the 49ers to rely on a last-minute signing.
Injury Woes: Kaelon Black Also Questionable
Rookie running back Kaelon Black is also questionable with a groin injury, an issue he has dealt with earlier in the season. When asked about his level of optimism regarding Black's availability, Shanahan quipped, "A questionable amount of optimism." Black, a dynamic playmaker out of Indiana, has yet to make a significant impact in his rookie campaign but was expected to contribute in a rotational role behind Christian McCaffrey. His potential absence further thins a backfield that already relies heavily on McCaffrey's versatility.
Defensive Challenges: Containing Mobile QBs and Fast Playmakers
The 49ers' defense has historically struggled against mobile quarterbacks, and they face another test in Dolphins quarterback Malik Willis. While Willis is no Josh Allen, his ability to extend plays with his legs could cause problems if the 49ers aren't disciplined. "Mobile quarterbacks have always stressed the 49ers’ defense," noted a Vulius Sports analyst. "It feels like, no matter the coordinator or the personnel, they’re always getting gashed by running QBs." The Dolphins also boast speedy running back De'Von Achane, who ranked fifth in the NFL with 1,350 rushing yards last season, and a receiving corps that can stretch the field. The 49ers' defensive line, led by Osa Odighizuwa, must win their matchups to prevent Miami from breaking off big gains.
Offensive Line Adjustments: Connor Colby's Transition to Left Guard
On the offensive side, the 49ers are working through a transition on the interior line. Second-year guard Connor Colby, who started at right guard for most of his college career at Iowa, is making the switch to left guard. "It’s kind of akin to going to a place like Australia, where you drive on the other side of the road — everything’s kind of flipped over," center Jake Brendel explained. Colby has been putting in extra work to make the adjustment, but he admits it's still a work in progress. "Right guard, I’ll always feel, is natural," Colby said. "But it doesn’t feel as awkward now." His development will be crucial in protecting quarterback Brock Purdy and opening lanes for McCaffrey.
Matchup Notes: Tight Ends and Rookie Defenders
The 49ers may look to exploit mismatches with tight end George Kittle, especially against rookie defenders. In their previous game, the Raiders' rookie safety allowed a touchdown to a running back on a play-action leak, and Kittle could find similar success underneath. Additionally, the Dolphins' secondary features rookie cornerback Jalen Johnson, who held up reasonably well in Week 1 but allowed a red-zone slant touchdown to Mike Evans. The 49ers' coaching staff will likely test Johnson with veteran receivers like Deebo Samuel and Brandon Aiyuk.
Game Predictions: A Decisive Win, But Not a Blowout
Despite the injuries and adjustments, the 49ers are favored to win. Tim Kawakami of The Standard predicts a 27-13 victory, while David Lombardi forecasts a closer 24-17 score. "This probably won’t look pretty," Kawakami wrote. "The 49ers built their schedule knowing they could pay for their Melbourne commitment with some wobbly legs in this one." Lombardi added, "I actually think Miami will give the 49ers a sweat, simply because I’m still worn out from the Australia trip and I did spy some tired players in the Levi’s Stadium locker room this week." The Dolphins, coached by former 49ers assistant Jeff Hafley, will aim to play spoiler with a scrappy performance.
