Vikings wide receiver Percy Harvin did not practice on Wednesday and is listed as day-to-day after spraining his ankle against the Seattle Seahawks on Sunday, according to Tom Pelissero of 1500ESPN.com.
Head coach Leslie Frazier said Harvin is "making improvements" and will be re-evaluated on Thursday. Harvin had two receptions for 10 yards and rushed four times for 24 yards against Seattle. Harvin is the Vikings' leading receiver with 62 receptions for 677 yards and three touchdowns in nine games this season.
Rookie wide Receiver Jarius Wright is taking Harvin's snaps in practice in case he is unable to play on Sunday when the Vikings host the Detroit Lions at home.
Harvin was on crutches on Monday and told reporters that he was a "long shot" to play this week.
Minnesota has lost two games in a row to fall to 5-4 on the season and trail the Chicago Bears by three losses in the NFC North division standings.
