Packers defensive tackle Letroy Guion has been suspended for the first four games of the 2017 season, a source tells Field Yates of ESPN.com (on Twitter). The exact reason for the ban is not yet known. Guion was previously suspended for the first three games of the 2015 season due to a violation of the league’s substance abuse policy. 
Guion, 30 in June, made 15 starts for the Packers last year and racked up 30 total tackles. He’s currently set to enter the second season of a three-year deal worth $11.25MM. Depending on the nature of the suspension, his guaranteed cash could be in jeopardy.
