Asa Jackson is the first Ravens draft pick to sign

The Ravens signed Asa Jackson on Tuesday, making the Cal Poly cornerback the first of their eight draft picks to agree to terms. The contract is a four-year deal, confirmed by a league source.

Jackson was a fifth-round pick in last month’s NFL draft. The 5-foot-10, 190-pound cornerback made eight interceptions during his Cal Poly career and also returned kicks and punts, averaging 14.7 yards on punt returns and 25.1 returning kickoffs. The Ravens have said Jackson will be part of the competition for returner duties and they also like the potential he brings to their secondary.

The Ravens selected Jackson, 22, with the 169th pick in the 2012 draft -- a compensatory pick.

The Ravens are working to get as many of their draft picks under contract as possible before this weekend’s rookie minicamp at the Castle in Owings Mills. They will also make it official with their rookie free agents before then, running them through physicals and then finalizing contracts.

The Carroll County Times first reported the signing.
