Fred Davis has been released by the New England Patriots.

Davis joined the Patriots on a one-year deal May 11, four days after being reinstated by the NFL from an indefinite suspension for a second violation of the league's substance abuse policy. When the suspension was announced in February 2014, Davis said he was being punished for taking a supplement that included a banned substance.  

Bill Belichick was asked about Davis on Tuesday.

"Fred's been here through the whole process, the OTAs; it's a different kind of system for him," Belichick said. "He's been out of football for a little while, but [he has] worked hard, very hard, to try to pick things up and learn a new system. He's making progress."
