Barton (back) has been ruled out of Sunday's game against the Trail Blazers.

EDGE Analysis

Just before tip-off, the Nuggets pulled Barton from the starting lineup after his back tightened up during pregame warmups. He was initially considered questionable to play off the bench, but the team has now officially clarified that Barton will not be available. Keep an eye on the veteran's status ahead of Monday's game at Dallas, which marks the start of a four-game Week 5 for Denver.
