Hiller, 38, hasn't played in the NHL since the 2015-16 campaign, but he spent the last four seasons with Biel HC in the Swiss league.
The southpaw signed with the Ducks as an undrafted free agent in 2007 and played in 328 games over seven seasons with Anaheim, including a league-high 73 contests in 2011-12. He ranks third in Ducks franchise history in wins (162), goals-against average (2.51), save percentage (.916), and shutouts (21).
Hiller spent two seasons with the Flames before heading overseas, joining them as an unrestricted free agent ahead of the 2014-15 campaign. He enjoyed a successful first season in Calgary, going 26-19-4 with a 2.36 goals-against average and a .918 save percentage during the regular season to lead the team to a surprise playoff berth and a first-round series win over the Vancouver Canucks. The 2015-16 campaign was not nearly as friendly to him, however, as he managed a 3.51 goals-against average and .879 save percentage in 26 games.
Hiller shined for Switzerland in numerous international appearances, but perhaps none more memorable than at the 2014 Olympics, when he posted a 0.67 goals-against average and .971 save percentage in three games. Unfortunately, Switzerland scored just three goals across four tournament contests.
