Mike Shanahan has emerged as a top candidate for the San Francisco 49ers' head coaching vacancy.

Shanahan interviewed for the job on Tuesday.

The 49ers are still in the mix for Tom Coughlin, but the organization has yet to make an offer to any of the candidates they have interviewed.

The 49ers are not believed to be waiting for any assistant coach from a team currently in the playoffs. 

The 49ers expect to name a head coach by the end of Friday.

Chip Kelly also remains under consideration and Adam Schefter reports the 49ers are likely to choose between he and Shanahan.
