It's Week 6 of the 2017 NFL season and Colin Kaepernick still does not have an NFL job.

Now he's planning to do something about his situation.

According to multiple national reports, the former 49ers quarterback is planning to file a grievance against the NFL owners for collusion.

Bleacher Report's Mike Freeman was first to report news of a grievance being filed. CBS Sports' Jason La Canfora has confirmed the news.

Kaepernick has hired attorney Mark Geragos, according to Freeman.

Kaepernick made national headlines last year when he started taking a knee during the national anthem to protest social injustice in the country. While some have argued that Kapernick simply isn't good enough as a reason why he hasn't signed, some believe he is being "blackballed" by owners who are concerned over possible negative reaction from fans.

Javon Kinlaw isn't afraid of a few deadly weapons.

The 49ers rookie showed off a seemingly dangerous drill on social media Friday in a video posted by defensive line trainer Cam Spence.

You're correct, those are in fact a pair of knives being wielded and sent in Kinlaw's direction as he bats them away. We've seen a similar drill from two-time NFL Defensive Player of the Year Aaron Donald.

Kinlaw was the 49ers' first selection in the 2020 NFL Draft, going No. 14 overall. The South Carolina product plugged up the middle for the Gamecocks' defense, picking up six sacks and recovering two fumbles. He likely will have an immediate chance to contribute, as All-Pro DeForest Buckner's departure to Indianapolis leaves a void in the 49ers' defensive line.

The rookie, along with a few returning players looking to earn a contract, will be imperative to make sure that void is filled in order for the 49ers to replicate the dominance the team enjoyed in 2019.

The Brandon Aiyuk hype among 49ers fans has grown exponentially ever since he was drafted 25th overall in April.

The sixth receiver to come off the board in the 2020 NFL Draft, Aiyuk is expected to make an immediate impact with his elite breakaway speed, which he showcased numerous times during his two seasons at Arizona State.

But based on the just-released Madden 21 ratings, Aiyuk isn't even among the fastest wide receivers in his rookie class. In fact, he's just the sixth-best rookie wideout according to the video game's new ratings, checking in at 72 overall.

The rookie receivers' overall ratings were almost identical to their draft positions, with the Denver Broncos' Jerry Jeudy and the Dallas Cowboys' CeeDee Lamb swapping places being the only alteration.

When it comes to speed, however, Aiyuk checks in as the 10th-fastest rookie wide receiver, behind a handful of players drafted well behind him.

Aiyuk's 40-yard dash time at the NFL Scouting Combine wasn't exactly elite (4.54 seconds), but during his senior season, he was tracked with a top in-game speed of 21.97 mph -- a mark bested by just three NFL players in 2019.

Game speed is different than track speed, and Aiyuk brings game speed in spades every time he takes the field.

There's a new WR in the Bay.

Guessing those ratings might be adjusted once Aiyuk actually sees some on-field action in a 49ers uniform.
