At 10:54 a.m. ET Tuesday, Sports Insights' Bet Signals triggered a Steam Move on the Jacksonville Jaguars for their NFL Week 1 matchup with the Kansas City Chiefs.
Steam occurs when multiple sportsbooks across the betting market all move their lines in the same direction at the same time, and is usually the result of professional bettors getting down large amounts of money and forcing adjustments from oddsmakers.
At first glance, it appeared as if sharp money was responsible for moving the line from Jags +4 down to +3.5.
However, around the same time, Kimberley A. Martin of Yahoo Sports tweeted that Chiefs wide receiver Tyreek Hill limped off the field after suffering a leg injury in practice.
While money from respected bettors is often the catalyze for major market adjustments, injuries to key players can also have the same effect, and that's what appears to have happened regarding Chiefs-Jaguars.
In fact, the Westgate SuperBook initially followed the move down to Kansas City -3.5 at approximately 10:58 p.m. ET, but after a tweet from ESPN's Adam Schefter revealed that Hill's injury is simply a bruised quad, the Las Vegas-based sportsbook returned the line to -4.

A handful of books have joined Westgate with the Chiefs as 4-point favorites, yet the majority of the NFL betting market is still holding at -3.5 at the time of writing.
According to The Action Network's public betting data, 56% of tickets wagered on the spread are backing Kansas City, while 64% of the money is on Jacksonville.
