It marks a return to Los Rayados for Pizarro, who initially left the club to join David Beckham's Miami side as a Designated Player for its inaugural 2020 season. The loan includes an option to make the move permanent.
"This loan gives the club more options to continue managing our roster. We are working tirelessly to acquire the right players that will help us attain our objectives moving forward. We're glad to have found an opportunity for Rodolfo to continue developing in Mexico and wish him well during his loan," said Inter Miami CF Chief Soccer Officer and Sporting Director Chris Henderson.
Pizarro appeared in 47 matches and tallied seven goals and 12 assists during his time at Miami, playing under coaches Diego Alonso and Phil Neville. He played 64 games with nine goals during his first stint with Monterrey.
The Tampico, Tamaulipas native won a Liga MX title in each of his stints with Pachuca, Chivas and Monterrey and also won the CONCACAF Champions League with the latter two sides.
By joining the defending CONCACAF Champions League winners for a second time, Pizarro is set to participate with Monterrey at the Club World Cup in February.
