Pollard was absent from Thursday's practice for personal reasons, Todd Archer of ESPN.com reports.
Per Michael Gehlken of The Dallas Morning News, Pollard wasn't present for drills Thursday, but there was no concern regarding his availability for Week 4 at the time of the report. Indeed, Pollard's absence isn't injury-related, so even if he remains away from the Cowboys on Friday, he appears to be OK as the team continues to prepare for Sunday's game against the Panthers.
