The L.A. Rams signed Luis Perez as an undrafted free agent in 2018, eventually making a brief appearance on the practice squad after being waived at final cuts. Perez made stops in the AAF, the XFL, and the USFL in the next four years, as well as brief periods with the Eagles and Lions, before eventually making his way back to the Rams this year. Perez spent almost a month on the roster, as the team needed more reinforcements in case Matthew Stafford couldn’t practice or if they needed a preseason quarterback, but he was released again on August 16.
