Try telling Erik Karlsson he has nothing left to play for.

The Ottawa Senators defenseman picked up an assist on Mika Zibanejad's first-period goal against the Florida Panthers on Thursday night, and it was a historic helper.

Karlsson's assist gave him 81 points this season, moving him past Nicklas Lidstrom for the most in an NHL campaign by a Swedish defenseman.

The Senators blue-liner matched the legendary former Detroit Red Wings rearguard with his 80th point Tuesday night against the Pittsburgh Penguins.

His 65 assists and 81 points are both career highs.
