Boyle, 34, recorded 24 points in 2018-19. He suited up in 47 games for the New Jersey Devils before being shipped to the Nashville Predators, where he played 26 games, for a second-round pick in the 2019 NHL Draft.
“With over 700 games played in the NHL and over 100 more in the playoffs, Brian brings a wealth of experience to our club,” said Panthers general manager Dale Tallon in a press release.
“He adds versatility and character to our lineup.”
The six-foot-six, 245-pound native of Hingham, Mass., was awarded the 2017-18 Bill Masterton Memorial Trophy following his return to hockey after being diagnosed with chronic myeloid leukemia.
Boyle has played in 766 NHL games, collecting 216 points, with stints with the Toronto Maple Leafs, Tampa Bay Lightning, New York Rangers and Los Angeles Kings as well as the aforementioned Predators and Devils.
He was originally selected with 26th pick of the 2003 NHL Draft by the Kings.
