McCain (lungs) was a partial participant at Monday's practice, Kyle Neubeck of AllPHLY.com reports.
McCain did everything except take part in the 76ers' final scrimmage of the day, so he doesn't seem to have taken a notable step forward in activity from what he did at Sunday's practice. The rookie is recovering from a pulmonary contusion, which he sustained on a hard fall to the court during a preseason game against the Nets last Wednesday. McCain hasn't yet been ruled out for Wednesday's season opener versus the Bucks.
