While the Baltimore Ravens announced John Harbaugh will return to the team next season, there could still be teams interested in pursuing him.

According to a source, it is believed the Miami Dolphins will still formally make a call to the Ravens on Harbaugh's availability. 

The Ravens play in the first round of the playoffs on Sunday, which could be a determining factor on whether they would be more willing to let him leave.

Stephen Ross pursued Jim Harbaugh in the past.
