As announced earlier this month, actor Marc Baylis has been cast as Rob, who turns up in Weatherfield following a stint in jail and turns to Carla for help in starting a new life.
Meanwhile, the role of Michelle's son Ryan has been recast after original actor Ben Thompson decided that he did not want to return to the cobbles.
Ryan will now be played by Sol Heras and arrives back on the street after being thrown out of university in Glasgow.

The two bad boys have been tipped to shake up life in Weatherfield this summer, and will even square up against each other when Rob decides to "teach Ryan a thing or two about family loyalty".
Coronation Street's producer Phil Collinson commented: "Carla's brother Rob is the latest in a long line of handsome Corrie charmers and is sure to set hearts fluttering in Weatherfield from the minute he arrives. The audience can expect thrills and a few broken hearts when this handsome bad boy hits town.
"Ryan returns carrying a dark secret and Michelle is going to have the fight of her life as she battles to get her troubled son back on the straight and narrow. Sol is a brilliant young actor and I'm so excited to welcome him to the cast."
