It's hard to blame the Detroit Lions for being upset at the officiating in their 23-22 loss to the rival Green Bay Packers on "Monday Night Football."

Lions defensive end Trey Flowers, who signed with Detroit as a free agent in the offseason after winning multiple Super Bowl titles with the New England Patriots, was called for two suspect illegal hands to the face penalties, one of which prolonged an early-fourth-quarter drive that ended with a 35-yard touchdown pass by Packers quarterback Aaron Rodgers. Flowers' first penalty came during a 3rd-and-10 play where the Lions sacked Rodgers. Green Bay likely would've punted, but the penalty resulted in an automatic first down to keep the drive alive.

Flowers was called for another illegal hands to the face penalty on Green Bay's final drive. This penalty crept the Packers closer to the end zone, and kicker Mason Crosby eventually converted a 23-yard field goal as time expired to seal a 1-point Green Bay win.

NFL Twitter, including several current and former players, were not pleased (or at least were confused) with the officiating. One of those players was Patriots linebacker Dont'a Hightower, who played with Flowers for three seasons. Here's a collection of notable Twitter reaction to the penalties on Flowers:
