The undefeated 49ers opened around -8 for tonight's matchup in Glendale, but were quickly adjusted up to 10-point favorites behind three-quarters of bets. With the range of numbers the spread has seen, both sides have attracted a fair share of sharp action at differing lines.

As for the professional action that's hit the total, it's been more one-sided, as revealed by Sports Insights' Bet Signals.

As of Thursday morning, five signals — indications of line moves caused by sharp action — have hit the under. We've yet to see a single one going the other way.

Also pointing toward the under being the sharp side, the 36% of bettors playing it have accounted for 50% of actual money being wagered. So while the money is split evenly, it's clear that bigger bets — the ones more likely made by pros — are banking on a lower-scoring game.

As you'd probably expect, sportsbooks are leaning toward the side of the sharps, even though it gives the majority of customers an easier over bet. After being listed at 44/44.5 early in the week, this total is down to a consensus 43.

It is worth noting, however, that all five Bet Signals came at slightly higher lines, with the lowest number hit being 44.
