In the 49ers first game with new Coach Jim Tomsula, the 49ers defeated the Minnesota Vikings 20-3 on Monday Night Football. Carlos Hyde in his first career start rushed 26 times for 168 yards and two touchdowns. Hyde's 168 rushing yards are the most by a 49ers player since 2012, when Colin Kaepernick rushed for 181 against the Packers. Colin Kaepernick went 17 for 26 with 165 yards passing. The 49ers defense was stout, holding the Vikings to just three points and sacking Vikings QB Teddy Bridgewater five times. Adrian Peterson, returning from suspension, rushed for only 31 yards on 10 carries. This game also marked the return of NaVorro Bowman, who missed all of the 2014 season with an injury. He had seven tackles and a sack in the season opener. In addition, the 49ers introduced black alternate uniforms.
