Rotherham are the only other club on young Boro defender Dael Fry’s CV to date. Following his breakout season with Boro, the England youth international spent the first half of the 2016/17 season at the New York Stadium, making ten appearances. Former Boro captain Grant Leadbitter also spent time on loan with Rotherham in the early days of his career.

A Boro Academy graduate, Dormanstown midfielder Richie Smallwood debuted for the club in 2010 - the first of 72 appearances for the Teessiders. In 2013, he joined The Millers - then a League One side - on loan. He helped Rotherham achieve promotion to the second tier, scoring the winning penalty against Leyton Orient at Wembley. The switch was made permanent, with Smallwood enjoying a further three years with the South Yorkshire club before linking up with his former Boro boss Tony Mowbray at Blackburn Rovers in 2017.

Another Redcar native (although he represented Scotland at international level), Robbie Stockdale also featured for both clubs. In the wake of seven seasons with the Boro, the reliable right-back joined Rotherham on loan in 2003 and would enjoy two campaigns there before moving across Yorkshire to Hull City. Stockdale was a coach with Sunderland and temporarily caretaker manager before the arrival of Jack Ross saw his time with the club end last summer. He's now assistant manager at Scottish Premiership side Hibernian. 

Mercurial Argentine Emmanuel Ledesma was loaned out to Rotherham during his three-year spell with Boro, and rejoined the Millers at the end of his contract with the Teessiders. He made only a handful more appearances there, and even fewer with Brentford, his last club on these shores. Having since spent time in Greece, Ledesma has since reignited his career across the Atlantic, becoming a prolific scorer for first the New York Cosmos in the NASL and, since January 2018, FC Cincinnati in the United Soccer League.

Another with a nomadic career that links our two clubs is Josh Walker. An FA Youth Cup winner with Boro and a regular with England’s youth teams, the midfielder scored his first career goal on loan at Aberdeen (against Bayern Munich, no less) before another impressive spell with Rotherham, scoring three times in 15 games for the club as they reached the League Two play-offs. Walker has since played for a host of other EFL clubs, more recently enjoying a successful stint with Bengaluru FC. He now turns out for Edinburgh City, who are currently third in Scottish League Two.

Having come through the ranks at Leeds United and helping Southampton to back-to-back promotions, Frazer Richardson joined us for one season in 2013/14, making 11 appearances for the Teessiders. Rotherham-born, Richardson made the switch to his hometown club when his time at the Riverside came to a close. The right back played 40 times for the Millers after they earned promotion to the Championship. He finished his career with another South Yorkshire side Doncaster in 2016.
