Kelvin Benjamin began the opening few minutes of his first training camp practice with the Giants on Wednesday engaged in an intense conversation with head coach Joe Judge. A moment later, Benjamin made a slow walk off the field, trailed closely by general manager Dave Gettleman, who when he was the GM in Carolina, made Benjamin a first-round pick of the Panthers in the 2014 NFL Draft.

Benjamin might as well have kept on walking. The Giants released him later in the day. A source told The Post Benjamin’s weight was “an issue.’’

The 30-year-old was an extreme long shot to make the final roster. He has not played in the NFL since 2018 and was trying out at a new position, tight end. The Giants took a flier on Benjamin, signing him May 16 out of a rookie minicamp to a one-year deal worth $990,000.

Benjamin told that he arrived at camp at 268 pounds and that Judge wanted him to weigh in at 251. Benjamin passed the conditioning test on Tuesday, but said Judge told him he was going to fine him for being overweight and that he could not practice on Wednesday.
