Update: Karlsson will likely need at least six months of recovery time on his lacerated Achilles tendon, the Ottawa Citizen reports.
Recommendation: The news came out after Karlsson's surgery on Thursday. If everything goes according to plan he should be set to return around mid-September, which is when training camp begins for the 2013-14 season. We can expect Sergei Gonchar and Patrick Wiercioch to see increased ice time in his absence.
