CHARLOTTE, N.C. -- Carolina Panthers quarterback Cam Newton was back throwing on Monday, his first participation in a full practice since suffering fractured ribs during an Aug. 22 exhibition game at New England.

Newton said last Wednesday he had no doubt he would start in Sunday's opener at Tampa Bay, and nothing he did early in practice would dispute that.

The first pick of the 2011 draft, who hasn't missed a start at Carolina, showed no limitation in his throwing motion. He ran between drills, something he didn't do all of last week, and had a full range of motion during stretching.

Newton was wearing a larger flak jacket than the one he was wearing when New England linebacker Jamie Collins stepped on the back of Carolina's franchise quarterback at the end of a 7-yard run to cause the fracture.

He did not appear hindered by that.

Also back at practice after sitting out the exhibition finale at Pittsburgh were defensive ends Charles Johnson (hamstring) and Greg Hardy, (shoulder) and right guard Trai Turner (groin).

Turner started the first two preseason games before suffering the injury. The team released Chris Scott, who started the last two preseason games, on Saturday.

Either Turner or Fernando Velasco, signed in July, is expected to start against Tampa.

Backup quarterback Derek Anderson, who suffered a bruised hand against the Steelers, showed no ill effects from the injury.
