It appears as though Robinson will miss all of training camp, and could even begin the 2015 season on the team’s reserve/PUP list, which would cost him the first six weeks of the season.
Goessling mentions that the Vikings could use first-round pick Trae Waynes in a more prominent role this season following the injury to Robinson.
Robinson, 24, is entering the final year of his four-year, $3.015 million rookie contract and stands to make a base salary of $766,000 for the 2015 season.
In 2014, Robinson appeared in all 16 games for the Vikings and recorded 40 tackles, three interceptions and eight pass defenses. Pro Football Focus has him rated as the No. 32 cornerback out of 108 qualifying players.
