Door Open For Colin Kaepernick: NFL World React

Free agent Colin Kaepernick may still be able to sign with an NFL team 

but the door is reportedly open for him to do so.

The former San Francisco 49ers quarterback worked out for the Las Vegas Raiders earlier this week. 

Kaepernick worked out with an NFL team for the first time since he left the league after the 2016 season.

The Raiders have not made a decision on whether or not to sign Kaepernick. 

Insider Ian Rapoport of NFL Network says the "door is open."

The door is open..." he tweeted. " 

Sounds like it went well and he impressed.".

Derek Carr is the Raiders' quarterback 

but they could use some veteran depth behind him

Kaepernick has had the support of Raiders 

owner Mark Davis for years.

Kaepernick's future with the Raiders will be fascinating to watch. There would certainly be a lot of fan appreciation, no doubt
