Has Rishard Matthews' steady and productive run with the Titans come to an end?

The Tennessee wide receiver took to Instagram on Wednesday to leave a cryptic message regarding his future with the team. At 7:42 p.m. ET, he posted a photo of his family with the caption: "When Daddy's home for good. That is unless someone calls him to get off the couch."

Titans coach Mike Vrabel said earlier Wednesday that Matthews had missed practice because of personal reasons.

Shortly after his Instagram post, Matthews told Austin Stanley of A to Z Sports that he has reached an agreement with the Titans for his release.

"EVERYTHING IS GOOD! JUST WASN'T HAPPY WITH WHAT WAS GOING ON," he told the website via text message. "BARELY GETTING ANY PLAYING TIME. IT WAS TIME TO MOVE ON."

Matthews also added: "I've been the leading (Titans) receiver for two years. Then all of a sudden I'm barely playing and not even starting. Using my injury as the scapegoat. Look at number of snaps and targets."Matthews missed all of training camp due to a knee injury, and his start to the regular season has been extremely underwhelming: three catches (on six targets) for 11 yards through the team's first three games. He played 36, 28 and 31 snaps through the Titans' first three games, respectively.

A seventh-round draft pick by the Dolphins in 2012, Matthews has been one of the Titans' most consistent players offensively since the team acquired him via free agency in 2016 on a three-year, $15 million deal. He had 65 catches for 945 yards and nine touchdowns in 2016 before racking up 53 catches for 795 yards and three touchdowns last season.

In August, Matthews signed a one-year contract extension with the Titans through the 2019 season.

The Titans (2-1), who host the Philadelphia Eagles (2-1) on Sunday (1 p.m., FOX), are already without tight end Delanie Walker, who the team placed on injured reserve after he suffered an ankle injury in the season opener against the Dolphins on Sept. 9. Without Matthews, they would will rely on Corey Davis, Taywan Taylor and Tajae Sharpe for the bulk of their receiving targets, with Darius Jennings and Nick Williams as their fourth and fifth receivers.
