The Jets continued their aggressive offseason to upgrade the defense Wednesday by reaching a three-year deal with 49ers cornerback Donald Strickland, a source said.
Since the start of free agency, the Jets have been seeking a veteran cornerback to go with Darrelle Revis and Lito Sheppard. They looked at Corey Ivy of the Ravens and former Ravens cornerback Samari Rolle.
Other terms of the deal weren't immediately available.
The 5-10, 187-pound Strickland will be joining his fourth team. He was a third-round choice of the Colts in 2003. He went to the Eagles in 2005. He spent the past three years in San Francisco.
In three seasons with the 49ers, Strickland had 10 starts.
