5 Things To Know About The Seahawks' Week 15 Opponent, The San Francisco 49ers

Learn more about Seattle’s Week 15 opponent and NFC West rival, the San Francisco 49ers.

ttk week 15

The 7-6 Seahawks are home for Thursday Night Football's NFC West rematch against the 9-4 San Francisco 49ers. With injuries causing a facelift to the depth chart of both teams, Week 15's matchup also has much at stake for a pair of teams with playoff aspirations. Here are five new 49ers developments to watch for since the teams met in Week 2.

Brock Purdy or Josh Johnson: Quarterback Carousel

The 49ers were on their third starting quarterback when Brock Purdy took over for an injured Jimmy Garoppolo—Week 1 starter Trey Lance suffered a season-ending injury in Week 2 against Seattle—and now Purdy's availability is in question due to an oblique injury suffered on Sunday.

In his fifth-career game, Purdy completed 16 of 21 passes for 185 yards and two passing touchdowns, adding in a rushing score. Early in the first half, the Iowa State alum took a shot to the oblique that caused him to leave the game in the fourth quarter. Despite initial fears, 49ers coach Kyle Shanahan told reporters Monday that Purdy is "day-to-day."

Josh Johnson, meanwhile, has played for more than a dozen franchises. Last week, San Francisco signed Johnson off the Denver Broncos’ practice squad for his third stint with the franchise. Selected in the 2008 NFL Draft by the Tampa Bay Buccaneers, Johnson has played sporadically over his career as a journeyman. In 2021, Johnson started once for the Baltimore Ravens in Week 15's 41-21 loss to the Cincinnati Bengals. Johnson completed 28 of 40 passes for 304 yards and two touchdowns. Down several quarterbacks, San Francisco turned to Iowa State alum Brock Purdy, who suffered injuries to his oblique early in the contest. Johnson stepped in to complete 1 of 2 passes when called, after Purdy played through injury early in the fourth.

Head Coach Kyle Shanahan discussed bringing Johnson back and his capabilities under center.

"That's one of the reasons we brought him here," Shanahan said. "Just because Josh is really good at picking things up. He can go in, has really good command of the offense. It's Thursday, so no one is getting full speed reps, so that's always a challenge when you get in there but that was the situation for the quarterback last week too."

Christian McCaffrey: From Charlotte to the Bay Area

Since Seattle's Week 2 loss to the 49ers, San Francisco has added a dynamic weapon in running back Christian McCaffrey via trade with the Carolina Panthers.

After dealing with injuries in recent years with Carolina, McCaffrey is once again one of the league's most-versatile backs. In seven games with the 49ers, the Stanford alum has rushed for more than 400 yards and three touchdowns, along with 35 receptions for 316 yards and three scores. In Week 14's 35-7 win over the Tampa Bay Buccaneers, he rushed for a touchdown on 14 carries with 119 yards. Out of the backfield, McCaffrey made two receptions, one for a score.

Trent Williams: Large and In Charge

Year-13 shows no sign of regression for 49ers tackle Trent Williams. After ranking as Pro Football Focus' top-graded player for 2021, the Oklahoma alum is back atop the list. In addition to lead blocking for San Francisco's backfield, Williams leads all offensive linemen currently in Pro Bowl voting.

Seattle's defense will look to get around Williams - and get home to whoever Sunday's starting quarterback may be.

Talanoa Hufanga: Eye for the Ball

49ers second-year safety Talanoa Hufanga is developing into one of the league's best young ballhawks. Through 13 games, the USC alum's four interceptions tie for fourth-best across the league, along with seven passes defensed.

The hard-hitting safety is versatile, recording 70 combined tackles, 6.5 tackles for loss and a forced fumble.

Dre Greenlaw: Dre Day

Through 12 games played, 49ers linebacker Dre Greenlaw has surpassed his career-high in solo tackles (61) with 71 (103 combined). While the third-year Arkansas alum continues to develop into one of the league's best young run-stoppers, he's taken a leap in coverage as well. After playing just three games in 2021, Greenlaw has recorded four passes defensed and an interception. That pick came in Week 14's 35-7 win over the Tampa Bay Buccaneers, on future Hall of Famer Tom Brady.
