NASHVILLE, Tenn. -- Cameron Wake got his first four sacks this season and also forced two fumbles -- all in the first half -- and the Miami Dolphins routed the Tennessee Titans 38-10 on Sunday in Dan Campbell's debut as interim coach.

The Dolphins (2-3) came in having lost three straight, costing coach Joe Philbin his job Oct. 5.

With Campbell preaching a more fun and physical approach, the Dolphins finished with six sacks and intercepted Marcus Mariota twice. The rookie quarterback needed a knee brace and was replaced by Zach Mettenberger after the 2-minute warning.

Miami had been one of two teams in the NFL without a rushing touchdown, but Jarvis Landry ended the drought with a TD run, and Lamar Miller ran for 113 yards and a TD.

The Titans (1-4) lost their fourth straight, and their home skid is up to eight dating to last season.
