The Blackhawks agreed to one-year contract extensions with defenseman Michal Rozsival and forward Jordin Tootoo, the team announced Tuesday.
Rozsival's deal is worth $650,000 while Tootoo's deal carries a $700,000 cap hit, according to ESPN's Pierre LeBrun.
The move gives the Blackhawks two players eligible to be exposed during this summer's expansion draft.
NHL teams must expose two forwards and one defenseman that have played at least 40 games in 2015-16 or more than 70 in 2016-17, and they must be under contract in 2017-18.

Rozsival and Tootoo meet those requirements, which means the Blackhawks can now protect Ryan Hartman, who is also eligible.
