Rashaan Melvin DB

The Raiders and Melvin came to agreement on a one-year, $6.5 million contract Friday, Adam Schefter of ESPN reports.

Oft-injured during his five pro seasons, Melvin is coming off the healthiest stretch of his career, playing 25 games the past two years with the Colts after logging time in just 12 prior to that. He produced modest results on the field -- 96 tackles and three interceptions -- and should slot in as a starting cornerback in the Raiders defense. Expect Melvin to line up opposite 2017 first-round pick Gareon Conley.

The Colts placed Melvin (hand) on injured reserve Wednesday.

Melvin has acted as the No. 1 cornerback for an injury ravaged Colts secondary for much of the season, but he's been sidelined the past four weeks with a dislocated metatarsal on his left hand and didn't make enough progress in his recovery to gain clearance for the Week 17 matchup with the Texans. With Melvin unavailable for the season finale, Kenny Moore, Quincy Wilson and Nate Hairston should serve as the team's primary corners.

Melvin (hand) is out for Saturday's game against the Ravens, Zak Keefer of The Indianapolis Star reports.

As a result, Melvin will miss his fourth straight game. At this point, it would not be surprising to see the cornerback held out for the rest of the season. With Melvin out, expect Kenny Moore to see increased snaps in the Colts' defensive backfield.

Melvin (hand) has been ruled out for Thursday's game against the Broncos.

Melvin demonstrated some progress in his recovery from the hand injury by practicing in a limited fashion Tuesday and Wednesday, but the lack of a full session likely prevented him from gaining clearance to play on a short week. With Pierre Desir (shoulder) on injured reserve and Nate Hairston (concussion) set to join Melvin on the inactive list Thursday, the Colts could be quite vulnerable in the secondary.

Melvin (hand) participated in Tuesday's practice, Kevin Bowen of 1070 The Fan Indianapolis reports.

Melvin has missed the last two games with a dislocated metatarsal on his left hand, but his return to practice Tuesday is an encouraging sign for the defensive back on a short week. Should Melvin be able to put together another practice session on Wednesday, he could be set for a return to the field against the Broncos on Thursday.
