PSG's Ibrahimovic out of Lorient league clash
Paris Saint-Germain's Swedish forward Zlatan Ibrahimovic celebrates after scoring in Brussels on October 23, 2013
The Swedish striker had missed training on Wednesday, although his club have not specified the exact nature of his injury.
Ibrahimovic, who had scored nine goals in his last four games for his club before last weekend's 2-2 draw at Saint-Etienne, is joined on the sidelines by Thiago Silva.
The Brazilian defender has returned to training but is not yet ready to return from a thigh injury suffered towards the end of September.
However, the fit-again Javier Pastore is in the PSG squad for Friday's game, in which the reigning champions and league leaders will look to continue their unbeaten start to the season.
