49ers beat Jets as Jordan Mason steps up in place of injured Christian McCaffrey

The San Francisco 49ers shockingly saw Christian McCaffrey, their star running back, inactive on Monday night against the New York Jets. 

But his backup, Jordan Mason, did not disappoint in his first career start, as he helped lead his squad to a 32-19 win to start off the season on the right foot. 

All eyes were on Aaron Rodgers making his return to an NFL field after suffering an Achilles tear on the fourth play of the Jets' "Monday Night Football" matchup against the Buffalo Bills in Week 1.
