Giants Waive DB Mykkele Thompson; Add LB Jimmy Herman

The Giants have waived/injured defensive back Mykkele Thompson and have signed linebacker Jimmy Herman, who attended the team’s rookie minicamp on a tryout basis this year.

Herman, 6-3 and 224 pounds, played in 41 games for Purdue and was credited with 138 tackles (73 solo), including 85 for losses, and a half-sack. He will wear No. 49, and safety Trey Robinson has switched to No. 31.

Herman will provide depth at linebacker for Friday’s preseason opener. Linebackers Keenan Robinson (concussion) and Mark Herzlich (stinger) are not expected to play Friday.

Thompson, a fifth-round pick by the Giants in 2015 has been unable to stay healthy during his tenure. He missed his rookie season with a ruptured Achilles tendon suffered in the preseason. Last year, he suffered a season-ending foot injury in against the Saints.

Thompson, who hoped to convert from safety to cornerback this year, missed some practice time during the spring, including the three-day mandatory minicamp.

His injury woes continued into the summer, as he had been sidelined for several days with a quad injury.
