Fred Davis, Pats agree to 1-year deal

Former Washington Redskins tight end Fred Davis has agreed to a one-year deal with the New England Patriots, a source told ESPN NFL Insider Adam Schefter.

Davis joined the Patriots on Monday, four days after being reinstated by the NFL from an indefinite suspensionfor 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. He says it wasn't for marijuana, which was the reason for his first suspension.

Davis, 29, played 72 games with the Redskins from 2008 to 2013. A second-round draft selection in 2008, Davis has 162 career receptions for 2,043 yards and 13 touchdowns.

The Patriots are well stocked at tight end, with Rob Gronkowski, Scott Chandler, Michael Hoomanawanui, Tim Wright and rookie AJ Derby.

Chandler signed a two-year contract in March with a maximum value of $5.3 million. Gronkowski and Chandler project as roster locks, so the addition of Davis adds another layer of competition to the No. 3 and 4 spots with Hoomanawanui, Wright and Derby, a sixth-round draft pick.
