Sheffield United striker Oli McBurnie stepped off the bench as the mystery over his Scotland future continued.

The 24-year-old pulled out of the Scotland squad earlier this week with an apparent foot injury, but was named on the bench for Chris Wilder's men during a pre-season friendly.

That sparked a mystery with Scotland assistant Steven Reid saying he wasn't fit enough to join up with the Scotland squad for Nation's League games against Israel and Czech Republic.

Yet he was capable of playing 45 minutes against Derby in the 2-0 win for the Premier League outfit.

He was pictured celebrating with Billy Sharp after the Blades captain netted the second against Derby,

Earlier this week, Reid had said: "He's got an issue with his foot which has obviously not quite healed enough to meet up with us."

It's not the first time controversy has surrounded McBurnie and the Scotland squad since Steve Clarke replaced Alex McLeish as manager.

He was caught on camera admitted that he didn't want to go on international duty last year in a conversation with Blades team-mate John Fleck.

A line was drawn under it at the time with McBurnie apologising and insisting it was taken out of context.

The 24-year-old has struggled to make an impact with Scotland during his time in the squad.

He’s made nine appearances but is yet to find the target despite his impressive form and goal record at club level.
