Cornerback Pierre Desir has agreed to a new one-year deal with the Colts, a league source tells Stephen Holder of the Indy Star (on Twitter). 
Desir was claimed by the Colts in September of 2017 after he missed the Seahawks’ initial 53-man cut. The 27-year-old (28 in September) quickly impressed coaches and found himself with a prominent role behind top corners Nate Hairston and Rashaan Melvin. He appeared in nine games (six starts) for Indianapolis, finishing out with career highs in passes defensed (7) and total tackles (32) before landing on IR in December with a pectoral injury.
Now that Melvin has signed with the Raiders, Desir figures to be in for serious playing time right off the bat in 2018. The Colts likely will continue to look for cornerback help with Quincy Wilson, Kenny Moore, and Nate Hairston amongst their top CBs under contract. Darius Butler, who spent time at cornerback before playing primarily at safety in ’17, is in free agency limbo.
