Former NFL running back Brandon Jacobs reflected on his short stint with the San Francisco 49ers by ripping coach Jim Harbaugh in a radio interview.

"He is a b----, and that's why he's never won anything," Jacobs said of Harbaugh on WFAN’s “Boomer & Carton” show.

Jacobs signed with the 49ers in 2012 after spending his first seven seasons with the New York Giants, but he played only two games because of injury. Jacobs said felt like he being held hostage in San Francisco.

Jacobs was suspended by the 49ers for posting social media messages criticizing the team for his lack of playing time and eventually spent his final NFL season back with the Giants.

"I have one regret in my career, and that’s going to the 49ers when I could have stayed in New York,” Jacobs said. “I just wanted to see what stuff was like with another team and it didn’t work out.” “It is what it is,” he said. “I’ve got two rings. Harbaugh, though, he’s a b----. So it doesn’t matter.”
