Last week on "The Bachelorette," Desiree Hartsock had her heart broken by front-runner Brooks, who left the show early. But in a new interview, host Chris Harrison explained that he could still change his mind.

"It's absolutely possible for him to come back in the game," Harrison told reporters via a press call. "She may be open to it or maybe she learned her lesson and he's not the guy anymore. … He has a history of not quite being able to commit."

Harrison, who called the early departure a "curveball," added that during their conversation, Brooks seemed "wishy-washy."

"There are definitely regrets," he said. "He was in tears and emotionally crushed once Des started professing her love. He said as much."

But it's unlikely that Brooks would be next season's "Bachelor."

"He obviously has trouble committing and although he was sincere in coming on the show, he definitely has trouble expressing himself and letting himself be vulnerable when push comes to shove," Harrison said. "The reason the last two seasons have been so good is that Sean [Lowe] and Des did that really well. I don't know if Brooks has it in him to be so open."
