Mark Spector of Sportsnet first reported the deal.
Manning, 28, has appeared in only 27 of the Blackhawks’ 41 games this season, often as the result of a healthy scratch. He has just one goal and two assists in those games and has not played since appearing in just 13:20 of Chicago’s Dec. 12 game against the Penguins. Manning came to the Blackhawks after signing a two-year contract in the offseason worth $2.25 million annually. Manning’s contract does not include a no-movement clause.
Manning has a history with Edmonton captain Connor McDavid, too. Two years ago, Manning broke McDavid’s collarbone with a hit and later admitted intent in causing the injury, prompting McDavid to call Manning “classless.”
Edmonton general manager Peter Chiarelli reportedly received McDavid’s “blessing” before making the trade to acquire Manning.
Norell, 23, was a fourth-round selection of the Blackhawks in the 2013 NHL Draft and returned to his native Sweden for the 2018-19 season after playing three AHL seasons with the Rockford IceHogs.
Caggiula, 24, is in his third season with the Oilers, appearing in 29 games with seven goals and four assists with an average of 14:03 of ice time this season. He’s played in 156 total games in three seasons, peaking with 20 points in 2017-18. Caggiula is under contract through the 2019-20 season with a $1.5 million annual cap hit.
Garrison, 34, signed with the Oilers in October and has played in just 17 games this season, with one goal. His one-year, $650,000 contract expires after this season.
