49ers running back Brandon Jacobs has posted advice on Twitter with a reference to never working ''in a place where you hate your boss so much.'' The hash tag: ''YouLiveAndYouLearn.''
Jacobs had terrible timing with the tweet Thursday afternoon, considering San Francisco coach Jim Harbaugh was hospitalized for what the team called a ''minor procedure'' for an irregular heartbeat.
In the locker room soon after his post, Jacobs said people shouldn't ''assume'' his remarks were football-related, then followed up with more tweets - including one reading ''football is not my life.''
Jacobs, who dealt with a left knee injury early in the year, has been active only once all season but never played. He took the field for a play Oct. 18 against Seattle, then got called off.
