The Buffalo Bills weren't done with the Karlos Williams chapter just yet, but according to the latest information, the Bills decided against their initial request.

According to two separate reports, the Bills were going to workout the running back this week in Buffalo. Ryan Talbot of NewYorkUpstate.com was the first to report the workout, but then ESPN's Adam Schefter backed it up, adding the additional nugget that the Bills are likely to re-sign the 2015 fifth-round pick.

Since those reports, the Bills, once again according to Talbot, cancelled the workout Thursday afternoon.

A day before the news came out, Williams sent out this cryptic tweet:

The return is gonna be so sweet — Karlos Williams Sr (@Karlos_29_SR) October 5, 2016

Williams was released by the Bills on August 20, just hours ahead of the team's second preseason game of 2016. Not only had he been passed by on the depth chart, the running back went through a tumultuous offseason that included him showing up to offseason workouts both overweight and out of shape, starting training camp unable to practice on the Non-Football Illness list, and, of course, suspended for the first four games of 2016 for violating the league's substance abuse policy.

Four weeks have passed, and Williams remained a free agent all the way through, paving the way for the two sides to potentially reunite. The running back, even though he was not on an NFL roster, has already served his four-game suspension and would not have to miss any further time for that reason.

In only his second year, Williams does still have practice squad eligibility remaining, and the Bills could have signed him to the 10-man group. In his rookie season with the Bills, he played in 11 games while rushing for 517 yards, a yards per carry average of 5.6, caught 11 passes for 96 yards, and most impressively had a total of nine touchdowns.

The Bills would not directly address the Karlos Williams reports in any capacity.
