It appears the Saints reunion with Reggie Bush will take place this week in Detroit.

The Lions running back did not play in Sunday’s 17-3 win over the Minnesota Vikings because of a sprained ankle, but he told reporters Monday that he expects to take the field against New Orleans.

“Oh yeah, 100 percent,” Bush said, according to the Detroit Free Press. “Next week for sure.”

Bush has rushed 45 times for 161 yards and caught 20 passes for 142 yards this season for Detroit. A former first-round pick of the Saints, Bush spent his first five season in New Orleans, where he accumulated 4,232 yards from scrimmage and scored 29 touchdowns.

Bush was traded to the Miami Dolphins in 2011, where he spent two seasons before joining the Lions in 2013. This will be his first meeting with the Saints.

It is not yet known if wide receiver Calvin Johnson, who missed Sunday’s game with a high ankle sprain, will play this week.

Underdogs

It appears Vegas is losing confidence in the Saints.

In the early odds released Monday, the Lions are favored by 2.5 points over New Orleans this week. That number could move throughout the week, but this marks the first time this season the Saints have not been favored to start the week.

One thing that could swing things in favor of New Orleans is if Johnson is unable to play. But considering the Saints haven’t won a regular-season road game in 327 days, when they beat the Falcons 17-13 last season, it’s not surprising the oddsmakers like the Lions this week.

Receiving less

If the season were to end today, Drew Brees’ wide receivers would account for only 44 percent of his 1,574 passing yards. This mark would the lowest percentage posted by the Saints receivers dating to 2011, when tight end Jimmy Graham began to be a focal point of the offense.

This continues a downward trend by the receivers. In 2011, the receivers accounted for 52 percent of the yards. That figure climbed to 56 percent in 2012 but fell to 47 percent last year. In 2010, Graham’s first with the team, the receivers accounted for 67 percent of the passing yards.

That number will likely climb if Graham misses time with a shoulder injury. But if things remain on the same trajectory, New Orleans could be in danger of not having a receiver eclipse 1,000 yards this season.

Brandin Cooks (on pace for 816), Marques Colston (794), Kenny Stills (451), and Robert Meachem (192) are all on pace to fall well below the mark. Both Cooks and Colston need to average around 68 yards per game to hit 1,000 yards, while Stills needs 78 per contest.
