San Francisco 49ers quarterback Jimmy Garoppolo shared a fun fact with reporters on Monday morning. The wristband that he wore during his games with the 49ers was never actually used.

"We never used the wristband ... but it was there just in case," Garoppolo said. "Even when I was in New England, we always wore one just in case a headset goes out or something like that. It's kind of a little safety in your back pocket."

Cam Inman of Bay Area News Group asked Garoppolo if the headset ever went out during his time with the 49ers.

"Yeah it did, actually," Garoppolo answered. "It was at the Tennessee [Titans] game, beginning of the game. I was out there; I thought Kyle [Shanahan] was just taking a while to call the play. I looked over, and he gave me one of these. We just had to call the first one off the top of our head ... We only had like 10 seconds, so fast thinking and they executed well."

Garoppolo completed 120 of his 178 pass attempts for 1,560 yards, seven touchdowns, five interceptions, and a passer rating of 96.2 this season with the 49ers. Only three quarterbacks with 100-or-more attempts have a higher completion percentage than Garoppolo (67.4-percent) in 2017. They are Drew Brees (Saints), Case Keenum (Vikings), and Alex Smith (Chiefs).

Garoppolo's 1,542 passing yards through his first five starts with the 49ers are the most by a quarterback in franchise history in their first five starts with the team. The same total ranks fourth among all NFL quarterbacks in their first five starts. Only Drew Bledsoe (Bills), Trent Green (Rams), and Cam Newton (Panthers) had more.
