ALLEN PARK -- The news just keeps getting worse for Taylor Decker.

Last week, he allowed the most pressures in the league. This week, he has to face one of the most talented pass-rushing duos in the league. And he just might have to do it with a sore back.

Decker was limited in practice on Wednesday because of the injury. Cornerback Rashaan Melvin (knee), linebacker Jarrad Davis (ankle) and defensive lineman Da’Shawn Hand (elbow) were also limited. Nobody was out.

It’s unclear when Decker suffered the injury or if it impacted his play against Arizona, when he allowed a league-high seven pressures (along with teammate Rick Wagner and two others). He allowed two sacks, both of which led to fumbles, one of which was lost. And he committed four penalties, one of which was declined.

He ranked 61st out of 67 qualifying offensive tackles in Week 1, according to ProFootballFocus, and his pass-blocking ranked dead last.

Asked how concerned he was about Decker, offensive coordinator Darrell Bevell said: "I’m probably no more concerned than he is. I think that he is a very prideful guy. He’s really worked hard and he’s done an outstanding job this offseason of improving himself both as a player, but also as a leader for us on the offensive line. I expect him to be able to come back and be at his best this next week.”

The Lions will need Decker and Wagner at their best, given the challenge that awaits. Melvin Ingram and Joey Bosa form one of the best pass-rushing tandems in the league. Both sacked Jacoby Brissett in a season-opening win against Indianapolis on Sunday, and they combined for five hits overall. Now they face a Lions team that allowed Matthew Stafford to be pressured more times than any other quarterback in the league in Week 1.

Some of that pressure was allowed because of communication breakdowns up front, and Detroit has been busy trying to sort those out this week in anticipation of seeing a defense that has been using Bosa and Ingram more creatively.

“I think there are always communication issues that we sort through after every game where we have breakdowns in protection, or coverage, or whatever it is," head coach Matt Patricia said. "Part of that is trying to eliminate as much of those as possible as we go forward. Certainly, we have two really good defensive ends this weekend too. Obviously Bosa and Ingram, and they line up in different positions, so there is a lot of communication that has to take place with those guys. They’re on the same side, they’re inside, they’re inside they stunt outside, they’re outside they stunt inside. They just do a lot from that standpoint and communication will be a big part of that as we go forward.”
