Two Wolves players were barracked by Sporting CP fans during Saturday's 1-1 draw.
Joao Moutiho and Daniel Podence were whistled by Sporting fans whenever in possession during the preseason friendly.
Moutinho, who left the Lions heading to FC Porto in 2010, and winger Podence, who unilaterally resigned after the attack on Sporting's training HQ by ultras, were whistled whenever they touched the ball.
Neither player responded to the jeers, though Podence eventually saw yellow.
