The Lions have signed veteran tight end Levine Toilolo to one-year deal, a source tells Jeremy Fowler of ESPN.com (on Twitter). Toilolo spent the last five years with Falcons. 
The Lions have reinforced their tight end group after releasing starting tight end Eric Ebron earlier this month and allowing blocking specialist Darren Fells to leave in free agency. Toilolo and fellow free agent addition Luke Willson now lead the way at tight end for Detroit. 2017 draft pick Michael Roberts projects as their top TE in support.
The Lions also met with free agent tight ends Ed Dickson, Brent Celek, and Logan Paulsen this offseason, but Dickson and Paulsen have since signed elsewhere. Celek remains in free agency limbo, but it seems unlikely that Detroit will sign him after adding two other veteran TEs.
