The 19-year-old joins up with Rovers for the duration of the 2021-22 campaign as he builds up further experience at senior level.
A graduate of the Reds’ Academy, Clarkson has made three appearances for the first team to date, including a start in last season’s Champions League fixture at FC Midtjylland, and signed a long-term contract in the summer of 2020.
Blackburn finished 15th in the Championship last term, with Liverpool attacker Harvey Elliott enjoying a hugely productive spell on loan at Ewood Park during the season.
The Reds worked closely with Rovers manager Tony Mowbray and his assistant, Mark Venus, as they oversaw a campaign of significant development for Elliott, who thrived in their style of play with seven league goals and 11 assists.
