Heading into the preseason, the Buffalo Bills thought they had their receiving corps figured out, adding veteran Anquan Boldin to pair with star Sammy Watkins.However, Watkins has since been traded to the Los Angeles Rams and, on Sunday, Boldin surprisingly announced that he would retire prior to the 2017 season to focus on his charitable work.Now, recently acquired receiver Jordan Matthews is the top receiver in the Bills' lineup, which is not what the team expected at this point in the summer.With the departures of Watkins and Boldin, a tweet sent from the Bills' official Twitter account is now especially awkward. As you can see below, the picture featured Boldin and Watkins together with the caption "Did we just become best friends?":

If they did become best friends, it was a short-lived friendship, and one that won't see any on-field action together this fall.

Long-suffering Bills fans took to Twitter to roast the team for the now-awkward tweet on Sunday and Monday morning, with some of the best responses listed below:

Obviously, this isn't the first time in recent years that Bills fans have had a reason to vent their frustrations. The Bills are in the middle of the NFL's longest playoff drought and that doesn't seem likely to change this fall.

According to BuffaloBills.com, Boldin released a statement on his Twitter account, explaining his decision to focus on his humanitarian work:

"Football has afforded me a platform throughout my career to have a greater impact on my humanitarian work," the statement reads. "At this time I feel drawn to make the larger fight for human rights a priority. My life's purpose is bigger than football."

In his 14 years in the NFL, Boldin made 1,076 catches for 13,779 yards and 82 touchdowns. He made it to three Pro Bowls and won one Super Bowl during his time with the Baltimore Ravens.

Though Boldin's retirement caught the Bills by surprise, Buffalo general manager Brandon Beane released a classy statement wishing Boldin well in his charitable endeavors:

"We respect Anquan's decision to retire from the NFL," the statement reads. "We appreciate the time he gave us over the past two weeks. He is one of the best receivers to play this game and we wish him and his family all the best moving forward."

The Bills finished the 2016 season 7-9 and, based on the recent developments at the wide receiver position, that doesn't seem likely to improve in 2017.
