Johnny Manziel's season is over due to a concussion
Wednesday December 30th, 2015

Browns quarterback Johnny Manziel was diagnosed with a concussion Wednesday and is out for Sunday’s game against the Steelers, the team announced.

With Josh McCown already on injured reserve, Austin Davis will start for the Browns. On Thursday, Cleveland re-signed quarterback Pat Devlin and waived linebacker Jayson DiManche. Delvin signed with the Browns on Aug. 27, and played in Cleveland’s final preseason game before he was cut on Sept. 5.

Manziel was put through tests after he reported concussion-like symptoms upon arrival at the team’s facility on Wednesday. 

Manziel has started Cleveland’s last three games after being benched earlier this season for partying during the team’s bye week. After video surfaced of the bye week incident, Manziel reportedly lied about when it was filmed. Pettine said “the repercussions would be harsh” if it happened again.

When another video surfaced earlier this week of Manziel holding an alcoholic drink in his hand and singing, Pettine said he would speak with Manziel and didn’t rule out disciplining him. Manziel was also investigated by the NFL earlier this season for a domestic dispute that involved alcohol.
