Former 49ers QB Colin Kaepernick has been seen throwing a football for the first time in nearly a year. The 30-year-old was spotted working out in Houston on Thursday, showing off some impressive arm talent in a near 90 minute session. He went through a number of standard quarterback drills, throwing short and intermediate routes for the most part. He did unleash a few bombs downfield though...

Kaepernick's trainer, Josh Hidalgo, also posted this clip on Instagram of the free agent QB making some sharp throws. 

Hidalgo's post read: "I've been training @kaepernick7 everyday and to say he's dedicated is an understatement. Each day we hit the gym and put in work! We haven't stopped throwing, training and preparing since January of 2017. Even when we’re traveling we put in that work #nevertired 💪🏽 #imwithkap".

So, it appears that Kaepernick is working out on a daily basis, presumably with the hope of making an NFL comeback. 

However, nobody around the league seems to be aware or interested at this point. The Texans reportedly had no idea that the former niner was in town working out this week.

And, though some footage was released, the workout was intended to be a completely private one with staff closely monitoring the area and preventing members of the public from capturing video. 

Kaepernick hasn't taken a snap in the NFL since a week 17 loss to the Seahawks in the 2016 season. 

His political and social activism have left his playing career in limbo, with owners seemingly unwilling to attach their brand to him. Despite the lack of interest, Kaepernick can clearly still sling it, and his production over his six seasons in the league speaks for itself.

In 69 games with the niners, he threw for 12271 yards, 72 touchdowns and just 30 picks. He also added 2300 rushing yards and 13 scores on the ground. 

His dynamic playmaking ability helped take San Francisco to a Super Bowl and NFC Championship game in consecutive seasons in 2013 and 2014. He broke Michael Vick's NFL record for rushing yards by a QB in a playoff game against Green Bay in 2013,  rushing for 163 yards on 12 carries.

The former second-round pick out of Nevada has all the physical tools to help a quarterback-needy team, but it will seemingly take a lot for any team to look past the media thunderstorm that would come their way should they sign him. 

The media negativity and lack of interest from teams doesn't seem to deter Kaepernick from working at his trade though.

He seems to still love slinging the ball around, and it would be a shame were he to never step on an NFL field again.
