David Long

Linebacker David Long is out for the second straight week with a hamstring injury.

The Tennessee Titans will be without three players who are in the concussion protocol as they prepare to face the Houston Texans on Sunday.

Starting right guard Nate Davis, third-down back Jeremy McNichols and starting tight end Geoff Swaim are all in the concussion protocol and won't play Sunday for the 8-2 Titans.

Other Titans who were declared out for Sunday included three other starters in outside linebacker Bud Dupree (abdomen) and inside linebackers Rashaan Evans (ankle) and David Long (hamstring). Cornerback Greg Mabin (ankle) is also out for the game.

With Davis out, it likely means that Aaron Brewer will start at right guard. The Titans offensive line has been a makeshift group most of the season, having not had one single game where all five starters started and played from start to finish.

McNichols' absence means the Titans will have to figure out a way to divide up the third down carries. Both Adrian Peterson and D'Onta Foreman will have to pick up some of the slack as outlet receivers and in pass protection. Practice squad running back Dontrelle Hilliard is also an option to be elevated for the game.

Swaim was added to the injury report with a concussion on Thursday, and the Titans will be relying on MyCole Pruitt and Anthony Firkser to fill in. Tommy Hudson, who was designated for return from injured reserve is a possibility to be activated if he is ready.

Defensively, the Titans added outside linebacker Derick Roberson back to the roster from injured reserve and he will help offset the loss of Dupree, who did not practice all week and lasted only one snap in last Sunday's win over the Saints.

Starting inside linebackers Long and Evans will give way to veteran Jayon Brown and rookie Monty Rice, but the Titans will be thin behind them.
