If the pair had any hope of playing together it has been swept aside by Belgian coach Marc Wilmots, who briefly experimented with them up front in tandem against Colombia.
With his side falling to a 2-0 home defeat, the boss insists it is not a tactic he wants to repeat.
Benteke started the game, and Lukaku was brought off the substitute's bench in the 58th minute.
18 minutes later, Benteke was taken off with a slight knock, but it sounded like Wilmots had seen enough anyway.
He said after the game: "Voila, I'm glad you have seen it. I wanted to try it, but soon saw that nothing was going to be working."
Belgian newspaper Nieuwsblade reported: 'The contribution of Lukaku to play alongside Benteke was not a success.'
Lukaku was brought on with Belgium 1-0 down, but as they chased the game they were left further exposed and conceded a second before Benteke was taken off the field.
It is a disappointment for both strikers, who could have saved themselves a lot of anxiety had they hit it off straight away.
With both players having a point to prove and wishing to make their respective cases, Premier League defences are going to be the losers, and their clubs the winners.
