Colts will be without two players against the Falcons

Braden Smith: 

The Colts will again be without starting RT Braden Smith this week. He has still not practiced since he left the team's Week 13 matchup with the Tennesee Titans with a knee injury. This sets up rookie Blake Freeland to make his ninth start of the season, which will officially give him more starts on the year than Smith (eight). Luckily for the Colts, their Week 15 opponent is the Atlanta Falcons who lack a game-changing pass rusher. No player on the Falcons has six sacks on the season; their team leader is Arnold Ebiketie, who has 5.5. 

Segun Olubi: 

For the 2nd straight week, the Colts will be without LB Segun Olubi. Olubi has been a key special teamer for the Colts this season. And his playing time has increased since the release of Shaquille Leonard. He has flashed in the run game as a rotational LB and looks to be a solid development piece for the Colts LB room.
