The Detroit Lions are taking on the Minnesota Vikings on Sunday in a real NFC North showdown. The Vikings are undefeated going into the matchup. The Lions, meanwhile, hang on with a 4-2 record, so this game is crucial to both franchises.

During the game, however, Amon-Ra St. Brown left with an injury. That's a huge concern for Detroit. St. Brown is obviously their go-to wide receiver, and it's crucial that he's healthy for this team to thrive.

Amon-Ra St. Brown leaves Lions-Vikings game to be evaluated for head injury

The Lions suffered a concerning moment early in Sunday's matchup against the Vikings when wide receiver St. Brown left the game to be evaluated for a head injury and possible concussion.

St. Brown went down hard while trying to catch a pass from Jared Goff in the back of the end zone. The 24-yard play was initially ruled a completion, but officials reversed the call after reviewing the play. St. Brown then headed to the locker room as Detroit's offense returned to the field.

The injury came during the first quarter, with St. Brown getting evaluated after the hard fall. He had already made two receptions for 11 yards before leaving the game.

The Lions were hoping to get their star receiver involved early, and the potential touchdown would have given him another chance to make an impact against Minnesota. Instead, the overturned ruling and his trip to the locker room quickly became the bigger story.

His status following the evaluation wasn't included in the initial report. Detroit will certainly be watching closely for any update on St. Brown as the game against its NFC North rival continues.
