Last week, wide receiver Terry Glenn revealed that the Cowboys were keeping him out of the team's off-season workouts. Now we know why.

According to Glenn, the team has asked him to sign a $500,000 injury settlement -- relieving them of any further obligation if he is sidelined for the season due to his surgically repaired right knee. If Glenn was injured without the waiver, the team would be on the hook for his entire 2008 salary of $1.74 million  So far, Glenn has declined to sign the waiver and has not been allowed to participate in the "organized team activity" workouts the past two weeks.

For the Cowboys, its simply a business decision. For Glenn, it's evidence that the Cowboys are not as confident in his recovery and rehab as they say they are.
