Locke, 28, is a former fifth-round pick by the Vikings in the 2013 NFL Draft. He finished his four-year rookie contract with Minnesota and reportedly had several teams interested in him this offseason.
The Colts signed Lock to a two-year, $3.45 million deal with $1.25 million in guaranteed this past March. Unfortunately, the Colts cut him loose coming out of the preseason.
The Lions signed Locke to a contract a few weeks into the regular season before cutting him loose. The 49ers brought him in for a workout earlier this week but did not sign him to a contract.
In 2017, Locke has appeared in five games for the Lions and totaled 1,140 punt yards on 27 attempts (42.22 YPA).
