Allen Park — The Lions officially waived offensive lineman Darren Keyton Tuesday, and he'll revert to season-ending injured reserve assuming he clears waivers.
Keyton, a Traverse City native, suffered a right knee injury in last Thursday's exhibition win over the Jets. Coach Jim Caldwell said Keyton's injury was related to his patellar tendon, which typically takes several months to fully heal.
With the transaction, the Lions now have an opening on the 90-man roster. The team worked out offensive linemen Saturday that could potentially fill his spot, though the Lions will have to start trimming the roster to 75 in two weeks.
The Lions also reached an injury settlement with tight end David Ausberry. He went on injured reserve last week with what ESPN reported was a broken finger, and the settlement will give him a chance to land with another team.
