Free-agent quarterback Colin Kaepernick is having a workout for NFL teams on Saturday. It appears the Denver Broncos will be one of the teams with a scout present for the action, according to Mike Klis of 9News.

The Broncos have experienced quarterback problems in 2019. Joe Flacco is set to miss the rest of the year, and second-round pick Drew Lock is out as well. That means they don't have their veteran leader or their rookie to take control of the team down the stretch.

Denver is 3-6 through the first 10 weeks of the season. While that does not bode well for them, the Broncos will still want to end the season strong.

Currently, they have Brandon Allen and Brett Rypien at the position. Rypien is the backup and an undrafted rookie with no NFL experience. Allen appeared in his first NFL game in Week 9 (Denver's last game).

Of course, Kaepernick has not appeared in an NFL game since 2016. In that year, he completed just 59.2% of his passes but did have 16 touchdowns compared to just four interceptions in 12 games. Meanwhile, he also ran for 468 yards and two more touchdowns on 69 carries.

It makes sense that a lot of teams will be interested in Kaepernick. He has proven in the past that he can at the worst be an exciting player that gives your team some life.

However, he also has not played in the NFL since 2016. That might make him rather rusty and might turn a few more teams off.

The Broncos are definitely a team that could use some quarterback help though, so at least going to see what he offers is a smart move.
