However, Rodgers refused to blame Reina for the error, describing the player as a "pivotal part" of the team.
He said: "Pepe has been brilliant since I've been here. He's been a pivotal part of how we work. He's been excellent off the field, a real good guy who understands the ideology of what we're trying to do.
"Unfortunately for goalkeepers it's part and parcel of the game. There's no blame attached - unfortunately for goalkeepers they make a mistake and sometimes it leads to a goal.
"An outfield player makes a mistake and they've got their mates to recover. It will happen sometimes but we move on."
The game finished 1-1 with Liverpool progressing 2-1 on aggregate after recording a 1-0 victory in the first leg at Tynecastle.
