ST. LOUIS (AP) - St. Louis Blues players are eager to follow up on the franchise's breakthrough 109-point season, even as they mentally prepare for possibility of a lockout.

The NHL collective bargaining agreement is set to expire Sept. 15, adding an element of tension to involuntary workouts. After an informal workout on Thursday, center Scott Nichol said it's just day by day.

The main sticking point in the impasse that threatens the upcoming season is hockey-related revenue. Defenseman Barret Jackman said the percentages don't add up, yet he is hopeful there will be movement in negotiations as the deadline nears.

Because of the uncertainty, some players have delayed coming to St. Louis. Training camp is set to open Sept. 21.
