EAST RUTHERFORD, N.J. — New York Giants quarterback Eli Manning has missed his second straight practice with an injured right heel.

Manning's streak of 82 straight starts seemed a bit more in jeopardy on Thursday when he was not on the field.

Backup David Carr again worked with the first team offense in preparation for Sunday's game at Giants Stadium against the Oakland Raiders.

Manning has said he could play even if he did not practice this week. He insisted Wednesday that the inflammation in his heel is progressing. However, he also said he would not play if either he could not run the entire game plan or he would risk making his injury worse.
