Quarterback Nick Mullens began the season on the practice squad, and he only took over as the 49ers' starter only when backup C.J. Beathard was unable to play due to thumb and wrist injuries.

But in the seven games Mullens has started for the 49ers, he has put up historic numbers.

On Sunday, Mullens completed 22 of 38 passes for 241 yards in the 49ers’ 14-9 loss to the NFC North-champion Chicago Bears. Mullens became the first 49ers quarterback to throw for 220 yards or more in seven consecutive games since Jeff Garcia in 2000.

Mullens also ranks third since 1970 for yards passing in his first seven NFL games. Here’s the complete list:

2,149 – Patrick Mahomes, Kansas City, 2018

2,103 – Cam Newton, Carolina, 2011

1,995 – Nick Mullens, 49ers, 2018

1,971 – Andrew Luck, Indianapolis, 2012

1,826 – Marc Bulger, St. Louis, 2002

--Tight end George Kittle had seven receptions for 74 yards. This season, he has put up the 49ers’ best receiving season since Hall of Famer Terrell Owens. Here’s the franchise’s top single-season receiving yards since 2000:

1,451 — WR Terrell Owens, 2000

1,412 — WR Terrell Owens, 2001

1,300 – WR Terrell Owens, 2002

1,228 – TE George Kittle, 2018

1,179 – WR Anquan Boldin, 2013

--Robbie Gould’s club-record streak of 33 field goals came to an end on Oct. 7. So what happened after that? The following week, Gould began a new streak. With three field goals on Sunday against his former team, Gould has now made 22 consecutive field-goal attempts, which ranks third in club history behind his own streak and Phil Dawson’s 27.

--Edge rusher Cassius Marsh recorded two sacks. Marsh, a fifth-year pro, has a career-high 5.5 sacks on the season and is tied with Ronald Blair for No. 2 on the team.

--Defensive tackle DeForest Buckner added to his single-season high in sacks. Here is a list of the 49ers’ most sacks in a single season since 2000:

19.5 – Aldon Smith, 2012

14.0 – Aldon Smith, 2011

12.5 – Andre Carter, 2002

12.0 – DeForest Buckner, 2018

9.5 – Bryant Young, 2000

--Rookie cornerback Tarvarius Moore made his first NFL start. He recorded his first forced fumble when he punched the ball out from Bears receiver Allen Robinson to provide the 49ers with one final chance at the victory. Greg Mabin came up with his first career fumble recovery.
