Houston Texans linebacker Azeez Al-Shaair wore “Free Palestine” cleats with Hamas propaganda scrawled on them during Sunday’s game against the Jacksonville Jaguars, in which the six-year veteran was ejected for delivering a dirty hit on quarterback Trevor Lawrence.

Lawrence sustained a concussion from the hit, which sparked an on-field brawl between the division rivals. The NFL is expected to suspend Al-Shaair for the hit, though it is unclear for how long, according to ESPN’s Adam Schefter.

Eagle-eyed fans noticed that Al-Shaair’s cleats featured the word “FREE” written in the colors of the Palestinian flag. Al-Shaair wears the cleats as part of the NFL’s “My Cause My Cleats” program to raise money for the Palestine Children’s Relief Fund, according to the Houston Texans website. That fund has faced scrutiny over its partnerships with Hamas-linked groups, according to NGO Monitor.
