New York Giants linebacker Jarrad Davis recently underwent knee surgery and is expected to miss significant time, a source told ESPN.
Davis, 28, was signed off the Detroit Lions practice squad late last season. He was active for one game before starting a pair of postseason contests for the Giants.
Davis also took reps with the first team defense this spring as second-year linebacker Darrian Beavers continues his recovery from a torn ACL. Another second-year linebacker, Micah McFadden, is also expected to compete for the starting job.
