Rotherham have signed teenage Arsenal defender Brooke Norton-Cuffy on a season-long loan.
The 18-year-old, who plays on the right-hand side, could make his debut in Tuesday's EFL Cup tie against Morecambe.
Brooke-Cuffy spent the second half of last season on loan at Lincoln, scoring once in 18 appearances.
He also featured in the England side that won the European Under-19 Championship earlier this summer.
