The Detroit Lions reportedly acquired cornerback Kevin Barnes from the Washington Redskins on Monday.

However, it isn't clear what the Lions sent to D.C. in exhange for the fourth-year defender.

MLive.com's Justin Rogers reported the trade Monday afternoon. His article didn't indicate who or what the Lions gave up for Barnes, a former standout at Maryland. 

Detroit gets a player that has played 29 games in a three-year span dating back to 2009. Barnes had a career-high 26 tackles in 2011 to go with four pass deflections. The 6-foot-1, 190-pound corner had a career-high five pass deflections in 2010.

"I'm excited," Barnes said of the trade, according to Rogers. "I guess they saw something they liked."

Barnes joins Alphonso Smith, rookie Bill Bentley, Jacob Lacey, and Chris Houston, among others, in the secondary. It's a unit that needs improvement, and scouting reports suggest that Barnes could do that for Detroit.
