What happened: The NFL issued a $12,537 fine to San Francisco 49ers linebacker Dre Greenlaw for unnecessary roughness during Week 7 action in Atlanta. League officials disciplined Greenlaw for delivering a blow to the helmet of wide receiver Drake London.

Why it matters: The sanction adds to recent disciplinary scrutiny for Greenlaw, who served a one-game suspension earlier in October following an altercation against Seattle. San Francisco dropped the contest 29-20, absorbing its first loss of the season while remaining in contention near the top of the NFC standings.

What to watch: The 49ers move forward into Week 8 looking to rebound and protect their standing atop the conference race.
