It appears Anquan Boldin is looking to make a comeback.

The Buffalo Bills, who still own the wide receiver's playing rights, have given Boldin's agent permission to talk to other NFL teams to gauge any potential interest in trading for the 37-year-old, a source with direct knowledge of the situation told NFL Network Insider Ian Rapoport. The Bills aren't interested in releasing Boldin's rights -- they are seeking to trade him if a team wants him, Rapoport reported.

ESPN first reported the development.

Boldin retired in August just weeks after signing a one-year deal with the Bills. He appeared in two preseason games with the Bills before announcing his retirement in a renewed effort to focus on social issues in the wake of racial violence that occurred in Charlottesville, Virginia.
