The 29-year-old United States international arrived at Ewood Park this week in a loan deal from Schalke until the end of the season and was thrown straight into the action at left-back.
Jones was made available for transfer by the Bundesliga side after three-and-a-half injury-plagued years but adjusted to the pace of the English game straight away and was influential both at the back and going forward.
Rovers boss Kean said: "He's not even fully fit. He has not played for a number of weeks but he's got everything. I tried to say to him at the end, 'just save your legs a little bit', but he finds that difficult, he wants to tackle and join in.
"His passing and the way he kept the ball for us as well was fantastic. He was a £10million player before his last injury and, with his performance in this game and another couple of games under his belt, I think he'll be fantastic for us."
