When the Nuggets open training camp Tuesday at Creighton University in Omaha, not every player will be full-go from the start.

Forward Darrell Arthur is working his way back from having a knee scope a few weeks ago. The veteran, who signed a three-year, $23 million contract extension in the summer, has been doing some work on the court but will be brought along slowly as the team gets into full drills.

The Nuggets have enough bodies to cover for Arthur’s reduced work, or most anyone else, as they are bringing 20 players into camp. Six of those players are vying for the final roster spot. But in a week-long camp featuring three two-a-day practices, keeping bodies fresh will be paramount.

Arthur is coming off a season in which he played 70 games and averaged a career-high 21.7 minutes, but did experience knee soreness at times. He’ll be in the mix for added playing time now that the Nuggets traded forward Joffrey Lauvergne to Oklahoma City late last month.

Meanwhile, rookie shooting guard Malik Beasley has been dealing with a stress fracture in his right leg, and while all signs are positive for him, the Nuggets won’t push him right out of the gate.

Beasley is able to do whatever he’s asked on the court, but the Nuggets played it cautious with him all summer. The late first-round pick was held out of summer league while the team’s medical staff got a firm grip on the situation and put together a plan of action to get him back on the court healthy with no worries of setbacks.
