49ers interview Robert Saleh and Lions assistant for defensive coordinator opening

Less than 48 hours after firing Nick Sorensen as defensive coordinator, the 49ers have turned to someone familiar as a potential replacement.

The team has interviewed former New York Jets coach Robert Saleh and current Lions defensive backs coach Deshea Townsend for the opening.

Based on what coach Kyle Shanahan said Wednesday, he’s just getting started. One of the reasons Sorensen was dismissed was the number of quality candidates available and Shanahan plans to take full advantage.
