The prank call to Shedeur Sanders during the NFL draft wasn't related to the ones other players received, a person familiar with the league's investigation told The Associated Press on Tuesday.
The person spoke to the AP on condition of anonymity because the investigation is ongoing.
Tyler Warren, Kyle McCord, Mason Graham and Chase Lundt also have reported receiving prank calls.
The call to Sanders, who was drafted by the Cleveland Browns in the fifth round, made headlines Sunday when the Atlanta Falcons said defensive coordinator Jeff Ulbrich's son was responsible. Sanders received a prank call on Friday night, the second day of the draft, while waiting after entering the draft expecting to be a first-round pick.
The Falcons released a statement saying 21-year-old Jax Ulbrich ''unintentionally came across the draft contact phone number for Shedeur Sanders off an open iPad while visiting his parent's home and wrote the number down to later conduct a prank call.''
The league provided phone numbers to teams for only the 15 players who attended the draft in Green Bay and the players who were participating in virtual interviews with NFL Network and ESPN. Sanders and Warren were among those doing virtual interviews.
Though Jax Ulbrich provided the number, he was sitting beside an unidentified friend who actually made the call to Sanders.
The Falcons said Jeff Ulbrich was unaware of the data exposure or the prank until after the fact. They offered ''sincere apologies to Shedeur Sanders and his family'' in their statement, and Jax Ulbrich also posted a public apology on social media.
