Chiefs' Chris Conley will miss Thursday's practice for NFLPA Rookie Premiere

The Kansas City Chiefs are already without two rookies (Marcus Peters and Steven Nelson) during OTAs due to the NFL and NCAA's rules on graduation dates. They'll have another one missing on Thursday.

Chiefs rookie WR Chris Conley will not practice with the team on Thursday as he attends the NFLPA Rookie Premiere this week in Los Angeles.

What is the Rookie Premiere?

More than 40 top rookies from the 2015 NFL Draft class will come together in Los Angeles May 28-31 to learn the business of football at the 21st annual NFLPA Rookie Premiere. A robust roster of business partners will be on site to grow their brands and create and promote their product lines through the utilization of group player rights.

The four-day event is hosted by the NFL Players Association, via its marketing and licensing arm NFL Players Inc.  It will also feature one of the most exciting moments for the rookies - wearing their official Nike team uniforms for the first time together during photo shoots with trading card companies Topps and Panini America at LA Memorial Coliseum.

Basically it's an opportunity for the players to meet these various brands and handle some of their business, such as posing for their rookie trading cards. I went to one of these a few years ago as a media member, which was pretty cool.

Conley will be back at the next set of OTAs next week but Peters and Nelson will remain out until mandatory minicamp in mid-June.
