Geno Smith's return to the starting lineup came to a premature end on Sunday, with the New York Jets quarterback exiting a 24-16 win over Baltimore with a right knee injury in the second quarter. In Buffalo, LeSean McCoy's nagging left hamstring issue flared up, with the NFL's second-leading rusher being forced to leave the Bills game at Miami in the third quarter. Bills safety Aaron Williams suffered a head and neck injury when Dolphins receiver Jarvis Landry was flagged for unnecessary roughness for a block in the second quarter. Washington cornerback Josh Norman was also forced to leave the Redskins game against Detroit, suffering a concussion and appearing to injure his left shoulder while defending a catch by the Lions' Marvin Jones. In Philadelphia, Eagles cornerback Ron Brooks was carted off the field after suffering a right knee injury late while making a tackle in the first quarter. The injury woes for Tennessee, which has already lost right guard Chance Warmack to injured reserve, continued with left guard Quinton Spain carted off with a right knee injury early in the second quarter.
