Former LSU and San Francisco 49ers safety Eric Reid has filed a collusion grievance against the NFL, hiring the same attorney who represents Colin Kaepernick.

His grievance is similar to that of Kaepernick's, according to ESPN. Kaepernick's grievance against the NFL centered around the belief he was unsigned by teams due to his protesting.

While teammates in San Francisco, Reid began kneeling with Kaepernick two seasons ago during the national anthem before games as a sign of protest. He stated his intent was to protest against racial inequality and police brutality.

Reid, a first round draft pick of the 49ers in 2013, earned a Pro Bowl selection in his rookie year, starting at strong safety each of the last 5 seasons. His rookie contract expired in March, and he remains unsigned.

"Our union is aware that Eric Reid and his legal representatives filed a collusion claim, which will be heard through the arbitration process as spelled out in our collective bargaining agreement," the NFL Players Association said in a statement today. "Our union supports Eric and we are considering other legal options to pursue."

Reid, 26, is a Baton Rouge native and was an All-American while at LSU.
