The Miami Dolphins are placing quarterback Tua Tagovailoa on injured reserve with the concussion he suffered Thursday against the Buffalo Bills, NFL Network reports.

It’s not clear from the report how long Tagovailoa will be sidelined. A stint on injured reserve means that Tagovailoa will miss at least four games. Per the report, Tagovailoa will continue to meet with independent neurologists as he goes through the stages of concussion protocol.
