The Hamilton Tiger-Cats have added two high-profile NFL quarterbacks to their exclusive negotiation list.

Former San Francisco 49ers quarterback Colin Kaepernick and ex-Washington Redskin and Cleveland Brown Robert Robert Griffin III are now among the 45 players for whom the Ticats have exclusive CFL rights.

Kaepernick has played six seasons in the NFL and made headlines last year for not standing for the U.S. national anthem. He has been a free agent since opting out of his contract earlier this month.

The 29-year-old threw for 2,241 yards, 16 touchdowns and four interceptions in 11 starts in 2016. He’s thrown for 72 touchdowns since joining San Francisco as a 2011 second-round draft pick.

Kaepernick rose to stardom under former Niners coach Jim Harbaugh, leading them to the 2012 NFC title, but he’s struggled in recent seasons and was benched for journeyman Blaine Gabbert last year.

The second overall pick by the Washington Redskins in 2012, Griffin III was the NFL Rookie-of-the-Year that season but he has been injury-plagued for much of his career after that. He’s still just 27.

Waived last year by the Redskins, Griffin signed a two-year, $15 million contract with the Browns but broke his right shoulder while trying to run out of bounds in the season opener against Philadelphia and missed 11 games. He returned for the final four games and led the Browns to their only win of 2016.

Over his four-year career – he missed all of 2015 due to injury – Griffin has started 40 games, throwing for almost 9,000 yards and 42 touchdowns.

The Ticats currently have three quarterbacks on the roster, including starter Zach Collaros.

Kaepernick and Griffin III become the latest big-name NFL quarterbacks added to a CFL neg list in recent months. Vince Young was added by the Saskatchewan Roughriders on Feb. 2 and ultimately signed with the team on March 11.
