While not every signing during free agency can be a blockbuster move, the Minnesota Vikings have been able to retain several of their own players while taking care of many of the exclusive rights and restricted free agents.
In fact, the Vikings announced on April 13, 2017 that Minnesota has come to put ink to paper on a deal with offensive lineman Zac Kerin, who showed some flashes in limited action during the preseason during 2015 and 2016.
Here is the tweet from the official Twitter account of the Minnesota Vikings announcing the transaction:
Kerin was an undrafted free agent in 2014 from Toledo before signing with the Minnesota Vikings.
