Everton manager David Moyes has promised not to push James Vaughan too hard as the young striker tries to enjoy a long injury-free run in the first team.
The 20-year-old striker has endured a succession of injury problems since making his Premier League debut in April 2005.
Vaughan has already featured in this season's clashes against West Brom and Portsmouth, but Moyes will not rush the forward.
The former Preston North End manager said: "He could be very exciting for us but my concern is that I've put in him too early because I've had very little options.
"The boy had to play 30 minutes at West Brom first up and I nearly had to take him off with ten minutes to go because he had nothing left.
"He's had no football but he made a difference and it's great for him to come back and show us what we've been missing.
"I don't know whether I could ask him to hang fire. His enthusiasm is his game although there are other parts that he needs to improve.
"Technically, we want to do a lot of work with him but his injuries have stopped us doing that. He's missed a lot of his young development because of that. But what he's got in abundance is enthusiasm."
