The Daily Mail says the 17-year-old striker came on as a substitute for Doncaster reserves last week against an experienced Rotherham side and impressed representatives from Everton, Sheffield Wednesday and Crystal Palace.
He was named Academy Player of the Year last year after scoring an impressive 26 goals and has continued his prolific form this term with 15 goals so far.
England U19 coach Sean O'Driscoll, a former Doncaster manager, has also been alerted to McKay's talents but the teenager qualifies for Scotland and the Republic of Ireland also.
McKay's twin brother Paul is a talented central defender also at Doncaster.
