This is not good. 

The Pittsburgh Steelers could be heavily shorthanded in Week 4 against the Minnesota Vikings in Ireland. 

The Steelers are listing Jaylen Warren, Jonnu Smith and Joey Porter Jr. as questionable to face the Vikings. 

The Steelers and Vikings are 2-1 on the season.

Pittsburgh beat the New York Jets in Week 1, lost to the Seattle Seahawks in Week 2 and beat the New England Patriots in Week 3. 

Meanwhile, the Vikings beat the Chicago Bears in Week 1, lost to the Atlanta Falcons in Week 2 and beat the Cincinnati Bengals in Week 3. 

Warren has carried the ball 43 times this season for 132 yards. He caught a touchdown pass from Aaron Rodgers in Week 1. 

Smith has 12 receptions for 65 yards and a touchdown. He also caught a touchdown from Rodgers in Week 1. 

Finally, Porter Jr. has only played in one game this season. He got hurt in the Jets game. 

Rodgers, one of the best players in NFL history, has faced the Vikings 30 times during his career. He has a passer rating of 105.4 with 7,401 passing yards, 59 touchdowns and 11 interceptions.

There were rumors that Rodgers could sign with the Vikings in the offseason instead of the Steelers. Rodgers and Minnesota head coach Kevin O'Connell are close friends. 

"I've known him forever, we've been friends forever, and we keep in touch," Rodgers said of O'Connell. "He's one of the guys I keep in contact with. Things never progressed farther than catch-up conversations. And I'll leave it at that."

Rodgers enters the Steelers-Vikings game with 586 passing yards this season. He has seven passing touchdowns and three interceptions.

"I can play better, for sure," Rodgers said. "You know, it's just about sometimes you just have to take what the defense gives you and be comfortable with that. Some of our best plays is just getting the ball into our playmaker's hands and letting them go. So I just need to be disciplined like I usually am and get the ball to the guys."
