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.
