Bills lock up two Kentucky rookies, leaving only one unsigned draft class member

The Buffalo Bills' draft class is almost completely signed, sealed and delivered.

The team announced the signing of two more draft picks on Friday, bringing the total to eight drafted rookies who are officially under contract.

Both Kentucky products made it official in Orchard Park with first-round cornerback Maxwell Hairston and fourth-round defensive tackle Deone Walker inking deals following a seemingly successful June minicamp. Terms of the contracts were not disclosed, but rookie contracts for drafted players are always four-year commitments with first-rounders also receiving a fifth-year club option.

Spotrac estimated that Hairston's deal is worth $15.2 million and requires $2.8 million in salary cap space this season.

Hairston appears to have dodged any type of serious injury after tweaking his hamstring late during Wednesday's practice. He's expected to be at full strength once training camp kicks off with the opportunity to earn a starting CB2 role.

Meanwhile, Walker, who has been brought along slowly by the Bills due to a back injury lingering from his final collegiate season, is trending in a positive direction. Head coach Sean McDermott noted that Walker has made progress health wise this spring with his reps ramping up at minicamp.
