A 2015 seventh-round pick, Robinson started five games in 2017 as a replacement. The 6-foot-7 offensive tackle has never stood out as more than a capable backup. The trade coming before cut downs for a later-round pick suggests Robinson was in danger of not making the Lions' roster.
Dave Birkett of the Detroit Free Press noted that Robinson left Thursday's preseason game with a foot injury, which he's dealt with in the past. The offensive tackle must pass a physical for the trade to go through.
