New England Patriots owner Robert Kraft will join a list of NFL figureheads to be deposed in connection to Colin Kaepernick's collusion case against the NFL, according to TMZ.

Kraft is hardly the first owner to be deposed in the case. Denver Broncos owner John Elway answered questions earlier this week at his team's headquarters in Colorado, while Houston Texans owner Bob McNair was questioned back in March.

Seattle Seahawks coach Pete Carroll and GM John Schneider were already questioned as well, along with NFL commissioner Roger Goodell, executive VP Troy Vincent, Dallas Cowboys owner Jerry Jones, Baltimore Ravens head coach John Harbaugh and general manager Ozzie Newsome.

Kaepernick filed a grievance against the league claiming collusion back in October, and remains unsigned by any team. The grievance claims the league is blackballing him for kneeling in protest during the national anthem while playing for the San Francisco 49ers.

Most of the other executives interviewed had potential quarterback openings that were not offered to Kaepernick. With Jimmy Garoppolo and Jacoby Brissett gone, Brian Hoyer and seventh-round pick Danny Etling are the two backup quarterbacks to Tom Brady on the roster.
