Sources have confirmed that Jacobson, a co-host of "First Take" on ESPN2, currently is serving a one-week suspension because of her behavior at a Jan. 11 roast for ESPN Radio personalities Mike Greenberg and Mike Golic at Atlantic City, N.J.
While declining to confirm Jacobson had been suspended, ESPN spokesman Josh Krulewitz said, "Her actions and comments were inappropriate and we've dealt with it."
At the roast, Jacobson made a rambling speech that included vulgar references about Notre Dame. Jacobson is a Michigan graduate, and she and Golic, a former Irish defensive lineman, often have exchanged barbs about the rivalry between the schools.
One eyewitness labeled it an "embarrassing display," and a newspaper account said the crowd booed Jacobson. Notre Dame coach Charlie Weis also was in attendance.
