Kalil was projected to be the Texans’ starting left tackle until the trade for LT Laremy Tunsil. He was also dealing with an injury.
Releasing Kalil frees up $3.25 million of cap space, according to Spotrac.
Kalil, 30, is a former first-round pick of the Vikings back in 2012. He played out his rookie contract with the Vikings before signing a five-year, $55.5 million contract that included $24 million guaranteed with the Panthers as a free agent in 2017.
Kalil was set to make a base salary of $7 million for the 2019 season when the Panthers released him. He signed with the Texans on a one-year deal worth up to $7.5 million.
In 2017, Kalil appeared in all 16 games for the Panthers and was rated by Pro Football Focus as the No. 55 offensive tackle out of 80 qualifying players.
