As Johnny Manziel prepares for his debut start Sunday against Cincinnati, he says the pro version of Johnny Football is new.

"I don't think you're going to see the Johnny that you saw at Texas A&M, because this isn't Texas A&M," he said Wednesday following his first practice as the Cleveland Browns' quarterback. "This is a different point in my life. I'm a different person than I was."

Manziel made light of a comment by Bengals coach Marvin Lewis, who called him a "midget" in a radio interview.

"It's absolutely funny," the 6-foot Manziel said of the remarks by Lewis, who has apologized several times. "I'm not going to sprout five inches over the course of the week, so my height is my height and I need to overcome it with other pieces of my game."

Newton to sit out

Cam Newton will not play Sunday against the Tampa Bay Buccaneers, allowing him a chance to begin recovering from an automobile crash that left him with two fractures in his lower back.

Carolina Panthers coach Ron Rivera confirmed that Derek Anderson will start, backed up by Joe Webb.

Newton was discharged from the hospital a day after his truck crashed and overturned in a two-car accident. Police did not blame either driver.

Gruden weighing options

Washington Redskins coach Jay Gruden didn't name his starting quarterback, in part to keep the firestorm over his choice from erupting, as happened earlier this season.

"I'm not going to announce [the starter] until I see the week of practice, see how it goes," Gruden said after Colt McCoy, Robert Griffin III, and Kirk Cousins took snaps.

McCoy, who was hurt Sunday, expects to start against the New York Giants.

Jags' Robinson on IR

The Jacksonville Jaguars are placing Denard Robinson, their leading rusher, on injured reserve with a foot sprain.

The Vikings have placed linebacker Michael Mauti on injured reserve. Coach Mike Zimmer said that Mauti needed minor surgery on his knee. The second-year player from Penn State has played mostly on special teams.
