Eventually there was another lockout in 2004–05, which resulted in that season being canceled altogether. On September 16, 2012 another lockout started, but it ended on January 6, 2013. The 1994–95 lockout had created resentment between the players and owners. When the next lockout happened in 2004 the owners attempted to come down hard on the players. In the end a salary cap for rookies was instituted, and all players signing a rookie contract needed to sign two-way contracts which allowed teams to send them down to minor league teams at minor league-level pay rather than the pay rate they received while playing for the parent NHL club. The league had expanded by four teams and began to participate in the Olympics. The league was to extend the CBA twice to ensure labor peace during that time. However salaries continued to rise, eventually hitting an average of $1.8 million and this was key in setting up the issues in the 2004–05 lockout.
