The 20-year-old striker turned up for the match against Walsall at the Millers training ground - Doncaster's Keepmoat Stadium.
When he eventually arrived at the Don Valley he admitted he was given a lot of stick for confessing his 'detour'.
"My mum won't be happy I admitted that," he said. "My head wasn't in the right frame and I went the wrong way. They absolutely caned me for it. I should never have admitted it.
"I should have just said I've been in traffic. But, you know me, I told them what happened and they absolutely ribbed me for it.
"I think my nickname is going to be Dopey before long, rather than Popey. I'm going to have to start switching on otherwise I'm going to be caned for the rest of my life."
