Players of Bobby Robins' ilk are a dying breed.

The hockey pugilist, who amassed 822 AHL penalty minutes before being promoted to the Boston Bruins at the beginning of last season, is calling it a day, announcing his retirement from professional hockey.

Robins appeared in three games for the Bruins, making his NHL debut in the 2014-15 season opener, days short of his 33rd birthday. Two games later, he fought Michael Latta of the Washington Capitals, suffering a concussion from which he could not recover enough to justify taking the ice again.

Robins told Mark Divver of the Providence Journal:

Hockey is what I know. It’s what I do. But after getting my head banged up like that, it was - no pun intended - a no-brainer for me. I couldn’t do it anymore. After the lowest points that I experienced, to where I am now, where I feel like myself again, there was no way I was ever going to risk getting hit in the head again or going through that again.

His hockey journey took him all over the world after he left UMass-Lowell in 2006, and Robins thanked the fans from all his teams over the years.
