Lions left tackle Taylor Decker will begin practicing on Wednesday, Ian Rapoport of NFL.com (Twitter link) hears. It’s a big step forward for Decker, who began the season the PUP list. 
When Decker takes the practice field, it will trigger a three-week window for the Lions to activate him. If, for some reason, he is not activated within those 21 days, the Lions will be unable to use him for the remainder of the year.
Decker was said to have a four-to-six month timeline when he suffered his shoulder injury in June and he has progressed well in his recovery. The Lions are eager to get the 23-year-old back on the field, particularly given the way fill-in Greg Robinson has performed. Robinson currently ranks as the fourth-worst qualified tackle in the NFL, per Pro Football Focus. To make matters worse, both Robinson and reserve Emmett Cleary missed Sunday’s game with ankle injuries and their status is uncertain for Monday night against Green Bay.
As a rookie, Decker was rated as the 23rd-highest tackle out of 78 qualified players, per PFF.
