The move helps Chicago offload $5.9 million in salary owed to Sharp, ESPN.com's Pierre LeBrun reported.
Sharp was a key contributor to the Blackhawks’ 2015 Stanley Cup run, scoring five goals and 10 assists in 23 postseason games.
Johns, a 23-year-old 2010 draft pick by Chicago, played with the AHL’s Rockford IceHogs during the 2014–2015 season.
Daley had the second-most points of any defenseman last year for the Stars, with 16 goals and 22 assists. He also scored six power-play goals for Dallas during the 2014–2015 season, among the most of any defender in the NHL.
Garbutt, 29, played parts of the past four seasons with Dallas, notching 30 goals and 40 assists in 198 games.
Dallas will retain 50% of salary owed to Garbutt for the 2014–15 season, meaning the Blackhawks only owe him $900,000, LeBrun said.
Chicago vice president and general manager Stan Bowman thanked Sharp for his contributions to the team via the Blackhawks Twitter account Friday night.
