Cleveland Browns QB Josh McCown (concussion) has not been cleared from the concussion protocol and will not practice Friday, Sept. 18, meaning QB Johnny Manziel will start in Week 2 against the Tennessee Titans. Manziel took all the first-team repetitions this week in practice, and he’ll make the third start of his career. Manziel was 13-for-26 with no touchdowns and two interceptions in his first two starts.
