Burban, 26, came on in the second half of Saturday's dramatic 26-24 win against England but tests on Monday confirmed the injury and forced him to pull out of the Italy clash.
Diarra, 30, was part of the Castres team that won the Top 14 title last season and has played for France before, in a 25-13 win against Italy in 2008.
He joins the 30-man squad which will be whittled down to 25 on Wednesday by coach Philippe Saint-Andre ahead of the match itself.
