J’Marcus Webb lost his starting spot on the offensive line last week and a pay cut came with it.

The Chicago Bears have given Webb a reduction in his base salary but he has the opportunity to earn all of the money back in playing time incentives.

A source with knowledge of the new deal told the Tribune that Webb’s base salary has been reduced from $1.323 million to the minimum for a fourth-year player -- $630000. That represents a savings of $693000 for the Bears against the salary cap right away something that was probably necessary with a tight cap and with cornerback Kelvin Hayden going on injured reserve and an injury settlement for defensive end Turk McBride.

So the move frees up cap space for the Bears this season and slots Webb at a more appropriate pay level if he is a backup now that he’s been relegated to the second team. Webb had to agree to take a pay cut. The Bears potentially could have advised him he would be released if he did not. At this point he’s still not a lock for the roster.

The Bears appear destined to use fifth-round draft pick Jordan Mills as the starting right tackle and that would leave Webb in a battle with Jonathan Scott for the swing tackle position. Scott has practiced only once since July 31 because of pain in his right knee but he had it drained a week ago and the hope is he can be back on the field this week. If Scott is healthy he could push Webb right out the door making the salary reduction a moot point.
