Boobie Dixon says his “time is up” in Buffalo

The Bills cleared nearly $13 million under the salary cap by releasing defensive end Mario Williams on Tuesday, although they also committed more than $13 million to left tackle Cordy Glenn by using the non-exclusive franchise tag.

That left the team with more work to do to if they want to have money to spend on left guard Richie Incognito and other players. They’ll get some from releasing offensive lineman Kraig Urbik and running back Boobie Dixon, who joined Urbik in saying farewell to the team on Twitter.

“Thank you to the Buffalo Bills organization and to the fans, my time is up, but you will always have a special place in my heart,” Dixon wrote.

Dixon’s departure will save the team $1.15 million under the cap. He ran 21 times for 44 yards and a touchdown in 2015. The Bills have LeSean McCoy, Karlos Williams and Mike Gillislee coming back at running back.

Tight end MarQueis Gray also said goodbye on Twitter, calling it “a pleasure” to have spent parts of the last two seasons with the team. There are no savings involved as Gray was set to be a restricted free agent, so not tendering him will just make him an unrestricted one instead.
