None of the betting lines for the 2015 NFL Divisional Playoffs have seen significant changes throughout the week, but one game has seen a shift in the points spread in recent days. With news coming out that Aaron Rodgers will be hampered by a slight tear in his calf, the Packers are the only favorites that aren’t giving their opponent at least seven points.

Green Bay is one of two undefeated teams at home this season, and they were named 6.5-point favorites over Dallas when the Cowboys beat the Detroit Lions and advanced to the second round. Rodgers played in the Packers’ final regular-season game, and there hasn’t been much doubt about whether or not he would play. However, the quarterback was forced to miss part of Green Bay’s Week 17 game, and the injury appears to be more serious than some had thought.

Denver is the only other team that didn’t lose at home in 2014, and they’ll host the final postseason game of the weekend. They’ve remained seven-point favorites over Indianapolis throughout the week. The Broncos beat the Colts in the season opener, but Andrew Luck and Co. didn't lose against the spread, something the team hasn't done against Denver in any of their last seven head-to-head meetings. Indianapolis has the best record against the spread this year, going 11-5-1.

New England is also favored by a touchdown in their matchup with Baltimore. Even though the Patriots are expected to win, the trends indicate that they might have trouble covering the spread. The Ravens have covered the spread in their last six postseason games, as well as their last three playoff games with the Patriots. New England is 3-10 against the spread in their last 13 postseason contests.

Seattle is, by far, the biggest favorite of the weekend, making Carolina the first double-digit underdog of the 2015 playoffs. The Panthers have lost 13 of their last 14 games when getting at least 10 points, and the Seahawks have won 28 of their last 30 contests when giving their opponent at least 10 points. Neither team has lost since November, combining to win nine games by double-digits in their current winning streaks.

Below are updated Las Vegas betting odds for the second round of the NFL playoffs. Two of the point spreads and three of the over/unders have decreased since the lines opened.

Baltimore Ravens (+7) at New England Patriots, 47.5

Carolina Panthers (+11) at Seattle Seahawks, 39.5

Dallas Cowboys (+5.5) at Green Bay Packers, 52.5

Indianapolis Colts (+7) at Denver Broncos, 54
