The Lions signed tight end Dorin Dickerson after a workout Monday, according to Dickerson, who announced the signing via his verified Twitter account.
The team officially announced the move Tuesday.
The team waived receiver Patrick Edwards, who hasn't had the impact the team had hoped after winning a starting job out of training camp, to make room for Dickerson on the 53-man roster.
Edwards had just five catches for 46 yards on the season and missed two games because of a high ankle sprain. He was targeted three times in Cleveland and failed to make a catch.
Dickerson caught nine passes in 11 games with Buffalo last year and was released at the end of the preseason.

"Him and (Theo) Riddick are still being evaluated," head coach Jim Schwartz said Monday when asked about Scheffler. "They didn’t make the trip (to Cleveland), but we’ve done that with a lot of guys that have been concussed.
"Travel is one of the things that can potentially set guys back -- the pressurized environment on the plane, and stadiums and stuff like that. So both of those guys didn’t travel with us this week. They’re still being evaluated, so that’s really all I have to say there."
Riddick also suffered a concussion in Green Bay and was briefly taken to the hospital during that game.
A former University of Pittsburgh product, Dickerson (6-1, 226) was the fastest tight end at the 2010 NFL Combine, running the 40-yard dash in 4.4 seconds. He was a seventh-round pick by Houston that year.
