Lions lose center Frank Ragnow to knee injury in first half against the Saints

The Detroit Lions went the first two seasons of Dan Campbell's tenure as head coach without having all five projected starting offensive lineman on the field for a single snap together. This year, that lasted one game. Left tackle Taylor Decker played through much of Week 1 with an ankle injury, then he missed two games.

More recently, left guard Jonah Jackson missed five of six games with two separate injuries-an ankle (three games) then a wrist (two games), But the Lions' left guard was back in the lineup for Sunday's game against the New Orleans Saints, and for just the fourth time all season the Lions had their starting offensive line together.

As expected, with all five starters in the lineup, one of the best offensive lines in the league was doing pretty well early on Sunday.

Center Frank Ragnow is managing an ongoing toe issue, and he occasionally pops up on the injury report with other ailment. But he generally suits up through whatever he's dealing with. The man's toughness cannot be questioned, he once played a game with a fractured throat.

About halfway through the second quarter, Ragnow got rolled up during a run by David Montgomery. He walked off the field very gingerly with trainers at his side, and he was carted to the locker room. It looked pretty serious all-around.

In the clip below, Ragnow is in the middle of the Lions' line (of course) and wearing #77. You can see how he got rolled up on.

The update came fairly quickly from the Lions that Ragnow is questionable to return to Sunday's game with a knee injury.

Update: As expected, Ragnow was ruled out during the third quarter.

Update, Part 2: After the game, head coach Dan Campbell had a mild level of optimism about Ragnow.

"We won’t know until tomorrow. At first, coming off, it sounded like one thing, and after the fact it sounded like something a little bit different (better). So one’s not as good. One sounds more positive. I won’t know until tomorrow.”

In Ragnow's place, right guard Graham Glasgow moved over to center and rookie Colby Sorsdal stepped in a right guard.
