Minnesota Vikings safety Harrison Smith left Sunday's game against the Chicago Bears, and his return is questionable as the team medical staff checks him for a concussion, according to Jon Ekstrom of the Vikings' PR team.
Smith left the field in the third quarter looking woozy and without balance after placing a hit on Chicago receiver Earl Bennett.
Smith has 56 tackles and an interception this season as a key contributor for the Vikings. He was drafted 29th overall in the 2012 NFL Draft and was on track to set a rookie record for the number of starts. Sunday's game was his 12th of the season, and Smith needs two more to tie the team's rookie record of 14 held by Chuck Lamson.
