Leidner, 23, wound up going undrafted out of Minnesota this March. Leidner previously tried out for the Ravens during their rookie minicamp but wasn’t signed to a contract following the session.
The Vikings signed him to a contract a few weeks ago before cutting him loose last weekend.
During his four-year college career, Leidner threw for 7,287 yards while completing 56.4 percent of his passes to go along with 36 touchdowns and 32 interceptions over the course of four years and 47 games.
Walters, 29, originally signed on with the Chargers as an undrafted free agent out of Cornell back in 2010. He lasted two years in San Diego before bouncing around with a few teams including the Vikings and Seahawks.
The Jaguars later signed him to a contract as an unrestricted free agent in March of 2015. He has been on and off of the roster over the past two years before returning to the team on a one-year contract this past March.
Unfortunately, the Jaguars released Walters from injured reserve with an injury settlement following this year’s draft.
In 2016, Walters appeared in 10 games for the Jaguars and caught 24 passes for 231 yards receiving and two touchdowns. He also contributed as a kick and punt returner.
