Smyth went down after a knee-on-knee hit from Colorado defenceman John-Michael Liles with 28 seconds left in Edmonton's 2-1 win Monday in Denver. Favouring his left leg, he had to be helped off the ice. The injury was described at the time as a charley horse.
Coach Craig MacTavish gave the players Tuesday off. Smyth was sore when he arrived at the rink Wednesday but suited up to prepare for the next game, a team spokesman said.
He leads the Oilers with 12 goals in 18 games.
