The Tennessee Titans have granted permission to the San Francisco 49ers to interview Titans offensive coordinator Mike Heimerdinger for their head coaching vacancy.
The interview is expected to take place either today or Tuesday.
Heimerdinger follows New England Patriots defensive coordinator Romeo Crennel to interview for the 49ers position, which became vacant when Dennis Erickson was fired last week.
Heimerdinger�s name first came up last week as a potential candidate, but the offensive coordinator told The City Paper at the time he had not yet been contacted.
