Browns rookie defensive lineman Myles Garrett has been placed in the concussion protocol.
The former No. 1 pick reported to the Browns practice facility Tuesday morning and complained of concussion-like symptoms. He will appear on today's injury report.
The Browns depart for London, where they'll face the Vikings, late Thursday.
Garrett, who dealt with a high ankle sprain at the start of the season, has appeared in three games and leads the team with four sacks.
