JAY-Z is reportedly upset with Colin Kaepernick over the way he handled his NFL workout.

The former San Francisco 49ers quarterback bailed on his private workout at the Atlanta Falcons training center on Saturday and held his own workout at an Atlanta-area high school instead.

According to ESPN, the NFL and Kaepernick’s representatives were at odds over the quarterback’s liability waiver and the overall transparency of the workout.

The league previously declined Kaepernick’s request to allow media into the workout. Kaepernick’s team also claims the NFL wanted him to sign an “unusual liability waiver.”

“The NFL has demanded that as a precondition to the workout, Mr. Kaepernick sign an unusual liability waiver that addresses employment-related issues and rejected the standard liability waiver from physical injury proposed by Mr. Kaepernick’s representatives,” his camp said in a statement.

However, the league has refuted his claim. “On Wednesday, we sent Colin’s representatives a standard liability waiver based on the waiver used by National Invitational Camp at all NFL Combines and by NFL clubs when trying out free agent players,” said the NFL. “At noon today, Colin’s representatives sent a completely rewritten and insufficient waiver.”

The league had planned to send video of the workout and an interview with Kaepernick to all 32 teams. Some scouts were reportedly impressed with Kap’s arms strength and talent, while others say he looked average at best.

“Our biggest thing with everything today was making sure we had transparency with what went on,” Kaepernick said following his workout. “We’ll be waiting to hear from [NFL commissioner] Roger Goodell, the NFL, the 32 teams.”

Now TMZ reports that JAY-Z feels that Kaepernick “turned a legitimate workout into a publicity stunt.” Source say that JAY is disappointed with the way things went down because he feels the league was genuine in trying to give him a shot.

Earlier this week, it was reported that the Roc Nation mogul was instrumental in trying to bring the two parties back together.

On his show, Dan Patrick said JAY-Z “was putting pressure” on NFL Commissioner Roger Goodell to give Kaepernick a workout and took a “reputational bullet” for the commissioner when he announced his partnership with the league in August.
