The margin for error for the Indianapolis Colts is very, very small for the last three games of the 2018 season. According to FiveThirtyEight, Frank Reich's squad has a 27 percent chance of reaching the playoffs and a 7 percent chance of winning the AFC South.

According to betting site Bovada, the Houston Texans are favored to win the South with -7000 odds. The Colts and Tennessee Titans both have +1600 odds to win the division.

It is a virtual certainty that the AFC West will send both the Kansas City Chiefs and Los Angeles Chargers to the playoffs, which means the Colts will either need to win the South or capture the second wild-card berth.

The Colts are one of six teams battling for a wild-card berth. Indianapolis will be at home for the next two weeks and finish the season with a crucial matchup on the road against the Titans.

Betting site Vegas Insider lists the Colts as having the seventh-best odds (40/1) to reach the Super Bowl. The Colts are behind other wild-card hopefuls: the Los Angeles Chargers (5/1) and the Baltimore Ravens (20/1) but still ahead of the Titans (50/1).

The Colts in Week 15 will welcome back center Ryan Kelly, who returned to practice Wednesday after sitting out two weeks with an MCL sprain.
