The Dallas Cowboys’ No.1 ranked offense isn’t 100% healthy going into Week 10. Amari Cooper is dealing with a knee injury that has his status for Sunday night’s game against the Minnesota Vikings in question.

It does sound like there’s a better chance than not that Cooper will be on the field, but it’s not a guarantee. The wide receiver underwent an MRI that revealed a knee bruise, forcing him to sit out Thursday’s practice.

Cooper told reporters that the injury is “manageable” and he hopes to play Sunday.

Dallas is a three-point favorite at home over Minnesota after winning two straight games. The Cowboys have a half-game lead over the Philadelphia Eagles atop the NFC East.

A quad injury limited Cooper to just one catch in Dallas’ Week 6 loss against the New York Jets. He limped off the field during Dallas’ Week 9 win over the New York Giants, but he caught a touchdown pass in the fourth quarter and finished the contest with four receptions for 80 yards.

Cooper has 42 catches for 701 yards and six touchdowns in eight games this season. Nearly 37% of Dak Prescott’s completions to wide receivers have been caught by Cooper in 2019.

Cooper has been one of the most important parts of Dallas’ offense since the team acquired him before the 2018 trade deadline.  The Cowboys are 12-5 with Cooper in the lineup.

Dallas has the NFL’s best offense by multiple measures. The Cowboys lead all teams with 6.7 yards per play, 436.8 yards per game and a 50% third-down conversion percentage.

The Cowboys are fifth in the NFL with 28.4 points per game.
