What happened: Frank Seravalli reported Chicago and defenseman Ethan Del Mastro agreed to a two-year contract with a $950,000 cap hit. The agreement came with players due to report for medicals and trimmed the NHL's unsigned restricted free agent list from six to five.

Why it matters: For the Chicago Blackhawks, the deal clears one contract item before camp logistics tighten. Around the league, the remaining unresolved RFA cases now include Adam Fantilli, Simon Edvinsson and Alexander Nikishin.

What to watch: Watch whether the remaining five RFAs land deals before full camp work ramps up. Chicago's next moves will show whether any other late offseason paperwork is still pending.
