Brown cannot play in the Patriots' season opener on Sunday night against the Steelers because he was not on the roster by 4 p.m. EST, but he will be eligible to debut with his new team -- his third in less than a calendar year -- in Week 2 against the host Miami Dolphins. According to Rapoport, via a league spokesman, Brown will not be allowed be around his teammates in any capacity in Week 1 because he is "not officially a member of the team."
