UPDATE: After the game, Stafford cleared concussion protocol.
Detroit Lions quarterback Matthew Stafford left the team’s Week 9 matchup against the Minnesota Vikings early in the fourth quarter to be evaluated for a concussion. The quarterback took a hit to the head on a play where he was sacked by Vikings linebacker Eric Wilson.
Stafford was pulled off the field and replaced by backup quarterback Chase Daniel.
Stafford was taken to the locker room after an initial check in the sideline medical tent.
The quarterback had completed 23 of 32 passes for 211 yards and a touchdown before leaving the game. He also threw two interceptions earlier in the game.
Detroit trails the Vikings 34-13 in the fourth, being carried by a huge game from running back Dalvin Cook, with 20 carries for 190 yards and two touchdowns early in the fourth quarter.
The Lions have lost five straight games against their division rival, and it will be six in a row barring a comeback.
