Peter Worrell was born August 18, 1977 in Pierrfonds, Quebec. The 7th choice, 166th overall selection of the Florida Panthers in the 1995 NHL Entry Draft, Worrell, listed at 6'6" and 235 lbs. was a member of the Hull Olympiques of the QMJHL before making his professional debut with the Panthers during the 1997-98 season.
In three seasons with the Olympiques (1994-97), Worrell was a two-time QMJHL champion and took part in two Memorial Cups, in 1995 and 1997, winning in the latter year. Worrell finished second in the QMJHL in penalty minutes during the 1995-96 season with 464 minutes, the fifth-highest total ever recorded in the league, while managing to score 59 points on 23 goals and 36 assists.
The 1997-98 season saw Worrell make his debut with the Panthers. Although he spent the majority of the season with the Panthers' AHL affiliate, the New Haven Beast, Worrell played in 19 games, registering no points and accumulating 153 minutes in penalties, and establishing himself as one of the league's top enforcers.
During the 1998-99 season, Worrell spent the majority of the season with the Panthers, while playing only a handful of games in New Haven. Finishing third in the NHL in penalty minutes with 258, Worrell also scored his first goal during the 1998-99 season, against the St. Louis Blues, and finished the year with four goals and nine points.
A knee injury during a pre-season game hampered Worrell's play during the 1999-00 season. Even though he managed to equal his point total from the previous year and register 169 penalty minutes, he missed 34 games due to injuries. A strong return in 2000-01 awaited Worrell as he played in 71 games, registering ten points and leading the Panthers once again in penalty minutes with 248. The hulking winger returned to the Panthers for his fifth season in 2001-02 and established at the time a career high 354 penalty minutes. Injuries hampered his season yet again in 2002-03, limiting the Pierrefonds, QC native to a mere 63 games and in the summer of 2003 had his rights dealt to the Colorado Avalanche.
