The 29-year-old forward has 12 points (seven goals, five assists) in 57 games with the Blackhawks this season. He has 138 points (60 goals, 78 assists) in 430 NHL games with the San Jose Sharks, Ottawa Senators and Blackhawks.
"There's some versatility there," Bruins general manager Don Sweeney said. "There's a player that played against us last year in the (Stanley Cup) Playoffs (with the Ottawa Senators), we know very well. Has been able to play up and down lineups from the teams he's played on. Plays at least two (forward) positions if not all three, kills penalties. Again, a character person, skates, physical. I think it's again just adding to the depth of the group."
The pick becomes a fourth-round selection if the Bruins advance past the Eastern Conference First Round of the Stanley Cup Playoffs or if they sign Wingels, who can become an unrestricted free agent July 1.
The Bruins (37-15-8) are third in the Atlantic Division, one point behind the Toronto Maple Leafs (with four games in hand) and four behind the first-place Tampa Bay Lightning.
The Blackhawks (27-28-8) are last in the Central Division and trail the Calgary Flames by 11 points for the second wild card from the Western Conference. Chicago has not missed the postseason since 2007-08.
The Bruins this week also traded for forward Rick Nash and defenseman Nick Holden in separate trades with the New York Rangers. Forward Ryan Spooner went from Boston to New York in the trade for Nash.
