Mark Bellingham, the father of Jude and Jobe Bellingham, has been told not to return to the Borussia Dortmund dressing room after his actions on Saturday.
Jobe has followed in the footsteps of his older brother Jude by joining Dortmund from Sunderland despite securing promotion to the Premier League.
The 19-year-old, who is not wearing 'Bellingham' on the back of his jersey, signed a five-year contract as part of his £27 million move and has been handed the No.7 shirt.
But the midfielder's Bundesliga debut did not go to plan as he was substituted at half-time of a 3-3 draw away at St Pauli.
Dortmund, managed by former Bayern Munich and Eintracht Frankfurt boss Niko Kovac, were 3-1 up but conceded two late goals to draw 3-3 in their opening game of the season.
Bellingham's parents Mark and Denise were in attendance and according to Sky Sports Germany, were not happy with his withdrawal after 45 minutes.
In fact, it's claimed they waited in the tunnel afterwards and Mark, who advises his son, sought out a conversation with Dortmund sporting director and former player Sebastian Kehl.

The outlet says the former Non-League footballer "made no secret of his opinion" but Kehl, who played 362 times for Dortmund, spoke after the game and confirmed that families will not be allowed access to any out of bounds areas in the future.
"We are all disappointed about the result yesterday. And still, the active area at our club remains reserved for players, coaches and officials, not families and advisors.
"This will not happen again. We have made this clear to all involved."
Bellingham joined Dortmund in time for the Club World Cup in the United States before featuring as a substitute in the 1-0 DFB Pokal win over Essen on Monday.
