Defensive tackle Corey Simon was placed on the non-football illness-injury list last week by the Colts because the team believes he didn't want to play football, according to a source close to the situation. He had arthroscopic surgery on his left knee in mid-August to repair some minor cartilage damage. The Colts had expected him back by the start of the season. But last week, he still was insisting his knee wasn't well enough for him to play. His weight, according to the source, also has been ballooning. When he played for the Eagles in 2004, he weighed about 305. When he signed with the Colts last season after sitting out training camp and all of the Eagles' offseason workouts, he was up to 325. Now, he's on the plus side of 350, the source said.
