Denver Broncos general manager and vice president of football operations John Elway has become the most recent NFL executive to be deposed in Colin Kaepernick's collusion case against the NFL, according to Mike Klis of 9NEWS.

Kaepernick was present for the hour-long session, which took place at the Broncos team headquarters on Tuesday.

Elway was the last executive to offer Kaepernick a roster spot, according to Klis. The Broncos tried to trade for Kaepernick before the 2016 season when he was a member of the San Francisco 49ers.

The list of individuals who have been deposed by Kaepernicks' lawyers continues to grow, and already includes Baltimore Ravens general manager Ozzie Newsome and head coach John Harbaugh, Seattle Seahawks general manager John Schneider and head coach Pete Carroll, as well as NFL owners Jerry Jones, Stephen Ross, and Bob McNair.

Kaepernick is attempting to prove NFL teams are colluding to prevent him from playing in the league, after he knelt during the national anthem to protest social injustice in the United States.

The quarterback has remained unsigned since opting out of his contract with the 49ers in March 2017.
