Lions' Ragnow carted to locker room after suffering knee injury against Saints

New Orleans — The Detroit Lions simply cannot catch a break along the team's offensive line. After getting Jonah Jackson back in the fold following a two-game absence, the team watched center Frank Ragnow exit the field and get carted to the locker room because of a knee injury suffered during the second quarter of Sunday's game against the New Orleans Saints.

Ragnow was blocking on a David Montgomery run when Jackson was blocked into him. Jackson's leg whipped around, making hard contact with the back of Ragnow's left leg, just below the knee.

Leaning on two members of the team's training staff for support, Ragnow slowly exited the field before he was loaded onto a cart to be taken to the locker room for further evaluation. He was officially ruled out of the game during the third quarter.

Following the game, Lions coach Dan Campbell said the locker-room evaluation provided some optimism, but the team won't know more until Monday, after Ragnow undergoes an MRI in Detroit.

"At first, coming off, it was sounding like one thing, and then, after the fact, it sounded like something maybe a little bit different," Campbell said. "One, not as good, (the latter) one sounds more positive. I won't know until tomorrow."

Ragnow was replaced at center by Graham Glasgow, who slid over from right guard. Rookie Colby Sorsdal came off the bench to backfill Glasgow's spot in the lineup.

A two-time Pro Bowler, Ragnow has made 10 starts for the Lions this season. He missed the team's Week 7 game against the Las Vegas Raiders with a chronic toe injury, which has cost him time each of the past two seasons.
