Kean told BBC Radio Lancashire: "Ruben Rochina will be in the squad [against Fulham on Saturday]. He has done well in training.
"He's starting to show signs that he's up to pace with the intensity of the training," the Scot added.
He continued: "If he doesn't start the game then I'm sure he will be involved against Blackpool on 19 March."
Valencia-born Rochina joined Barcelona at the age of 13 but failed to make a first-team appearance. He has represented Spain up to under-19 level and was part of the squad that reached the Uefa Under-19 Championships in France in 2010.
Rochina will become the fourth Spaniard to represent Blackburn following in the footsteps of Michel Salgado, Javier De Pedro and Yordi Gonzalez.
