 During the Packers' Week 5 matchup with the Detroit Lions on October 6, 2013, Matthews broke his right thumb and missed the next four games.On November 10, in a game at home against the Philadelphia Eagles, he returned to the playing field, donning a large "club" cast over his entire right hand.Without the ability to use his fingers to grab or apply pressure or leverage, Matthews was left to be fairly ineffective during this game.
