(CBS) The Blackhawks agreed to contract extensions with defenseman Johnny Oduya and forward Jamal Mayers Tuesday, bringing both unrestricted free agents back to Chicago for another season.

Oduya signed a three-year deal after playing 18 regular season games and six playoff games with the Blackhawks this past season. He was acquired from the Winnipeg Jets Feb. 27 before the trade deadline and led Blackhawks’ defensemen with three assists in the playoffs.

Mayers signed a one-year deal after playing 81 regular season games in his first season with the Blackhawks. The forward scored six goals and tallied nine assists and a team-high 91 penalty minutes in the regular season. Mayers was benched in the playoffs, however, and only played in three of the Blackhawks’ six postseason contests.

The Blackhawks also agreed to contracts with four former draft picks Tuesday. Forward Joakim Nordstrom, defenseman Klas Dahlbeck, and goaltenders Mac Carruth and Kent Simpson all agreed to three-year deals.
