In 1997, Maslowski signed as a rookie free agent with the San Diego Chargers, but was cut by the team prior to the start of the regular season.
This record would be surpassed by Nick Bolton with 180 tackles in 2022 In 2003, Maslowski's season, and ultimately his career, were cut short by recurrent knee injuries which he first sustained in 2001.
His MCL and PCL were completely torn from bone on his left leg and he underwent a tibial osteotomy which is designed to correct the alignment of the knee.
He was only the second professional athlete to attempt a return to playing after undergoing such a surgery, the other was Steve Yzerman of the Detroit Red Wings.
During training camp in the 2004 season, Maslowski attempted to make a comeback, but his left knee was not at full strength and the Chiefs placed him on the injured reserve.
