The Ravens are experimenting with different combinations on the offensive line, as coach John Harbaugh has promised.
That includes possibly using rookie Kelechi Osemele, who has started every game at right tackle, at left tackle.
Michael Oher, who was the starting right tackle last season, has been the starter at left tackle all season.
"I don't really know. We worked on everything especially in the bye week. We switched a lot of guys around," Osemele said. "Even I was at left tackle during the bye week. We're working on every different scenarios. … Worst-case scenarios."
Jah Reid, listed as a backup at right guard and tackle, coach John Harbaugh has more options.
"We got some guys that can get in there, rotate around," Osemele said. "Jah's back so that'll be good. We'll have a little more depth now."
Osemele injured his right ankle in the 43-13 loss to the Houston Texans. He had to be carted off the field and also had an issue with his right knee, but he was able to return in the second half as he avoided serious injury.
"I'm pretty much back to 100 percent. I'm as close as I'm going to be. I've been working on that over the bye. I'm getting healthy," he said.
Against the Browns, Osemele had trouble in the Sept. 27 game won by the Ravens 23-16. He failed to recognize their slow-developing stunts. With seven games under his belt, he doesn't expect to have the same problems.
"At first it started off being a little bit slow, being a rookie and everything … I know the system a lot better than I did starting out so just watching the last Cleveland game I've seen significant improvement," Osemele said. "I don't even seem like the same player as the first time we played.
"Just my technique overall significantly improved. Just recognizing things. Recognizing when a guy is going to slant. My awareness has improved. WIth that your footwork improves as well."
