A day after being put on blast by retired running back Brandon Jacobs, Jim Harbaugh has issued a response.

The Michigan head coach took to Twitter on Saturday to offer some “biblical advice” to Jacobs, who said on CBS Sports Radio’s “Tiki and Tierney” that Harbaugh “didn’t know what he was doing” with the San Francisco 49ers.

Jacobs doesn’t appear ready to make amends with his former coach, though.
