The Detroit Lions will reportedly be without their star left tackle for "a month or so." On Saturday, Ian Rapoport of the NFL Network reported that the Lions had placed Taylor Decker on injured reserve after he underwent finger surgery. 

Decker has been the Lions' starting left tackle for the last five years, and was selected by Detroit with the No. 16 overall pick in the 2016 NFL Draft out of Ohio State. While he's been a consistent presence on the Lions' offensive front, this is an interesting development, as it opens the door for No. 7 overall pick Penei Sewell

Sewell has been the starter at right tackle for the Lions in preseason, but the former left tackle has struggled in this transition. Sewell has been practicing on the left side since Decker suffered his injury, although first-year head coach Dan Campbell has not made an official decision on his replacement. 

"I'm definitely right tackle (when Decker comes back)," Sewell said, via the Detroit Free Press. "I look up to him, he's like a role model to me and that's that."

While left tackle is a tough position for a first-year player, it's possible Sewell could find more success at this spot. Either way, Lions general manager Brad Holmes isn't worried about Sewell and his development.

"I believe that he will be ready for Week 1 and I think he's ready now," Holmes said, via the Detroit Free Press. "Yeah, I mean, he's going through the normal process that a rookie would go through, regardless of where he's drafted. That's a tough position to play out there on that island and he's sat out for a year. So what he's done, and I know it's magnified by what may be a hiccup here or there, but there's so much of the good stuff that's maybe kind of hidden when you really kind of deep-dive the film, little subtle nuances that is going to make a big difference."
