Eli Manning

The father of New York Giants quarterback Geno Smith says he received a death threat last week before his son started Sunday in Oakland in place of Eli Manning.

The call came Tuesday, Geno Smith Jr. told NJ Advance Media, a little more than an hour after it was announced that his son would replace longtime Giants starter Manning.

"I was just at work," Smith Jr. told the website. "I answered, and he was like, 'Geno?' So I just listened, and he was like, 'Is this Geno?' I was like, 'Yeah.' He was like, 'Your son better not start or we're going to kill you.' I kind of just laughed and then he hung up."

Smith Jr. said he received another call Monday after coach Ben McAdoo was fired by the Giants. The Smiths did not inform the team about the threat, according to a team spokesman. NFL security was not told either, according to the NJ Advance Media report.

The Smiths didn't take the threat seriously.

"If someone was going to kill me, they ain't going to call me and tell me," Smith Jr. said.

Geno Smith consistently took the high road and said he tried not to listen to the hate coming from fans of Manning and the Giants after he was named starter.

His father handled the situation in a similar manner. He told his son about the death threat shortly after receiving the call.

"I think my dad handled it well," the quarterback told NJ Advance Media. "He kind of just hung up the phone. It's just kind of shameful that would be happening because of someone doing their job. When he told me that, I was like, 'What?' But you kind of get a sense of comfortability from him. He was like, 'Man, it's nothing. Don't worry about it. Just do your thing, play your game.' So that was why I was able to be easy with it."
