Teravainen has tallied six goals, 17 assists and 92 shots on goal through 33 games; his 23 points are second-most on the team. In December, he scored three goals and contributed seven assists in 13 games, including one goal and two assists in his first three-point game against the Chicago Wolves on Dec. 10.
Teravainen, a native of Helsinki, Finland, was selected by the Blackhawks with the 18th pick in the 2012 draft. In three games with Chicago last season he recorded four shots on goal and had an even plus-minus rating.
Teravainen, 20, is considered to be Chicago's best prospect. IceHogs coach Ted Dent has spoken highly of his performance in Rockford.
"Recently, yeah, for sure, he's playing better," Dent said. "The whole battle level and compete level just has to be there every night. It's tough ... Maybe he's gotten over that hump mentally."
The move comes after left-winger Kris Versteeg sustained an upper-body injury in Chicago's game against the Washington Capitals on Thursday. Chicago coach Joel Quenneville has said that Versteeg could be out "a bit."
The Blackhawks, 25-11-2 and second in the Western Conference, host the Dallas Stars (17-14-5) on Sunday at 8 p.m. EST.
