The Angolan forward, who scored five goals in his first five Championship games, was named the divisional Player of the Month for August - a remarkable return for the 22-year old.
He has played every minute of the Addicks campaign so far, and his goalscoring exploits make him largely responsible for their impressive start to the season - a start which sees them sitting in the play-off places after seven games.
However, the former Belgian Under-21 international suffered an arm injury with Wolves goalkeeper Carl Ikeme late on in Tuesday night’s 1-1 draw at the Valley.
Sky Sports is reporting that he is set to be monitored for the remainder of the week, and will face a late injury test to see if he is fit to take to the field on Saturday, when the Addicks head to Rotherham looking to extend their unbeaten start to the season to eight games.
If Vetokele does miss out on Saturday, Charlton will have lost their greatest attacking threat, with his tally of five just one fewer than the rest of his teammates have managed over the course of the season.
First choice strike partner George Tucudean has netted just once in seven games, whilst Simon Church has struggled to make a mark upon the first team, making just two substitute appearances with little effect.
Second highest goalscorer Yoni Buyens will be looking to fill the void left in Vetokele’s absence, although his tally of just two goals does not bode well against a hard working Rotherham team.
Icelandic winger Johann Berg Gudmundsson will also face a late fitness test, having missed the 1-1 draw with Wolves due to a groin injury picked up during the international break.
