Ferguson (knee) didn't practice Wednesday, Joe Hoyt of AllDLLS.com reports.
While he never stood much chance to practice three days after suffering a bone bruise and MCL sprain, Ferguson said Wednesday that his pain is already down to a "zero" on a 1-to-10 scale, per Patrick Walker of the Cowboys' official site. The injury clearly isn't as bad as it initially looked when he made an early exit from the Week 1 win at Cleveland, with Calvin Watkins of The Dallas Morning News reporting Wednesday that head coach Mike McCarthy is optimistic about Ferguson's chances of playing against the Saints this Sunday. Even if he doesn't end up playing this week, Ferguson should avoid a stint on injured reserve and push to return within the next few games.
