Vikings RB Adrian Peterson misses practice for court hearing

EDEN PRAIRIE, Minn. -- Minnesota Vikings running back Adrian Peterson missed practice Wednesday to attend a hearing in Minneapolis related to the NFL Players Association's lawsuit against the NFL on his behalf.

The union wants federal judge David Doty to hold NFL commissioner Roger Goodell in contempt of court for not following Doty's February order to vacate Peterson's suspension. After Doty ruled in favor of the NFLPA and Peterson, the league returned the Vikings running back to the commissioner's exempt list, where he stayed until April 16.

The NFLPA wants Doty to order the league and arbitrator Harold Henderson to issue a new ruling that reflects the judge's February order; it would ostensibly return some of Peterson's 2014 salary to him and prevent the league from enforcing its updated personal conduct policy in cases that happened before the NFL updated it last August.

Peterson is expected to return to Vikings practice on Thursday morning. He was one of five players to miss Wednesday's practice, joining center John Sullivan, tight end MyCole Pruitt, offensive tackle Carter Bykowski and cornerback Josh Robinson. Tight end Rhett Ellison left practice early.
