The former Plymouth Argyle player scored Charlton’s first goal in their League One play-off final victory over Sunderland at Wembley, providing added gloss to a renaissance spell on loan at the London outfit.
A peripheral figure for much of his time in South Yorkshire, Purrington heads back north with a promotion on his CV, but question-marks over his future at the AESSEAL New York Stadium.
On Exeter-born Purrington, who joined the Millers in a £300,000 deal from Argyle in January 2017, Barker said: “Ben has had a brilliant year. It is testament to Rotherham United that we are now able to send players out on loan who are playing regularly in League One.
“Scoring at Wembley was also amazing for Ben. I do not mind admitting that I jumped off my settee when Ben scored at Wembley as I was really pleased for him as he’s a lovely kid.
“Who is to say he cannot have a major part in what we do in the future? Ben wanted to play more regularly and that was understandable and should be commended.
“If it means we actually use him in League One, we have someone who was one of the most consistent players in the second half of the season and got promoted.”
