A.J. Brown dislocated his thumb during Monday's practice at Patriots camp but stayed on the field. The star receiver told NFL Network he didn't miss any reps after the injury. Brown's toughness through the mishap is notable given the Patriots' need for him to stay healthy this season. The team acquired him in a trade this offseason as part of their offensive overhaul, and losing him to injury would cripple their passing game. No word yet on whether the thumb will cause problems going forward, but Brown made clear he wasn't sitting out.
