The NFL asked Colin Kaepernick to sign a waiver that was very different from the one teams typically require players to sign for a standard workout.

“The waiver that Kaepernick was asked to sign on Saturday is essentially the same one he’d have to sign to work out for a team during the season,” said the NFL in the statement.

A typical waiver is focused on injuries with no acknowledgement that "Player acknowledges that he has been made no promise of employment, and understands that his participation in the Workout does not constitute employment” and no general waiver of “any and all claims . . . caused by, arising out of, occurring during, or related directly or indirectly to the Workout, Player’s presence at the Facility, and any medical treatment or services rendered in connection with or necessitated by Player’s participation in the Workout.”

Kaepernick and the NFL have a history of litigation, which makes him signing such a restrictive waiver arguably malpractice for his attorney.
