With Buffalo Bills' rookie cornerback Maxwell Hairston sidelined due to a knee injury, another rookie is getting a golden opportunity at more reps in training camp practice.

Buffalo Bills rookie cornerback Maxwell Hairston did not suffer a significant knee injury during training camp this week as initially feared after tests revealed no ACL damage and a LCL sprain, according to Ian Rapoport. Hairston could return as soon as three weeks and is not expected to miss any time long-term.

A person briefed on Buffalo Bills rookie cornerback Maxwell Hairston's injury says the first-round draft pick has been diagnosed with a sprained lateral collateral ligament in his right knee.
