The New England Patriots have had a busy Tuesday, so far. They held their fifth training camp practice today and announced the signing of four players. They also made another roster move, according to ESPN Boston's Mike Reiss:
The #Patriots have waived/injured rookie TE AJ Derby, sixth-round pick out of Arkansas.— Mike Reiss (@MikeReiss) August 4, 2015
The 23-year old Derby was drafted by the Patriots in the sixth round (pick 202) of this year's draft after having played his collegiate career in Arkansas. Derby joined a crowded tight end depth chart including roster locks Rob Gronkowski and Scott Chandler and thus was a longshot to make the roster in the first place.
It certainly did not help that he only practiced in the team's first training camp session last Thursday before sitting out the subsequent four sessions. This undisclosed injury is what led to him getting waived today. Since Derby was waived with an injury designation, Reiss notes that he will revert to injured reserve in case he is not claimed by another team. With the move, the Patriots' roster now stands at 89.
