Six players will not be practicing when the Carolina Panthers begin trading camp today. Five of those on the Panthers’ active-physically unable to perform (PUP) list — RB Jonathan Stewart, RT Jeff Otah, DT Louis Leonard, WR Steve Smith, and LB Thomas Davis — are on the mend from injuries.

The sixth player is offensive lineman Duke Robinson, who failed the conditioning test. Robinson being out of shape shouldn’t really come as a surprise. Check out what CBSSports.com/NFLDraftScout.com had to say about Robinson, who the Panthers took in the 5th round of the 2009 draft:

Work Habits: Robinson needs to have his offseason program monitored, as he does not show great work ethic (tends to get soft and overweight when not playing ball). He must keep his weight in check, as he has speed and stamina issues when he weighs more than 340 pounds (has ballooned to 380-plus pounds in the past). He will never be known as a great practice player and needs a “kick in the pants” every now and then (inability to follow team rules led to him being benched for the 2008 Chattanooga game and suspended for part of the Texas Christian contest).
