ALLEN PARK — Lions running back Kevin Smith, who sprained his ankle in the Thanksgiving game, is optimistic after completing a full practice on Thursday.

“Every day it’s getting better so at this pace I’m excited,’’ Smith said.

He would not put a percentage on his chances of playing on Sunday night at New Orleans.

“Every day I got better, today is Thursday I was able to practice the full practice,’’ Smith said. “I feel good, it’s still an ankle sprain, but it’s football.’’

Smith has played in three games since he was re-signed by the Lions after Jahvid Best sustained his concussion that forced him out for the season.

Against Carolina he had 16 carries for 140 yards, four catches for 61 yards and three touchdowns (two rushing).

He got off to a good start against the Packers (seven carries for 36 yards and three catches for 21 yards before he had to leave the game with the ankle injury.
