ALLEN PARK, Mich. -- The Detroit Lions have been spending part of the offseason trying to upgrade their secondary.
The 26-year-old Vaughn played college ball at Ole Miss and went undrafted in 2010. He spent two seasons with Denver before heading to Indianapolis for 2012 and 2013.
He played in every game for the Colts over the past two seasons and has played in 54 games in his NFL career, making 116 tackles and intercepting five passes. He has also recovered four fumbles in his career.
Vaughn adds to a large group of cornerbacks already on the roster, including veteran Chris Houston and younger players Darius Slay, Bill Bentley, Jonte Green and Chris Greenwood. The Lions are also expected to add a cornerback during May's NFL draft, perhaps even with a first round selection.
