Bent had to miss just over a month of football after picking up a hamstring problem, but he did make his return in the Rams last fixture against Wolverhampton Wanderers.
It was a comeback that was made ahead of schedule, but Bent says that he has not felt any repercussions from rushing his return.
“I got told a timeline, from when I did the initial injury away at Fulham, of four to six weeks," he said. "In the week leading up to the game at Wolves I felt comfortable, I felt like I was moving a lot quicker and I was delighted to get back out on the pitch.
“I was out running a couple of days earlier than I should have been and was hitting top speeds days before I was meant to be. I didn’t want to hold myself back any longer. There were no problems after the game.”
The news means that Bent should be fully up to speed after the international break, and that can only be good news for Derby.
The Aston Villa loanee was in brilliant form prior to his injury and Steve McClaren's men struggled to cope in his absence.
Derby have failed to win any of their last six fixtures, but the hope is that Bent's clinical finishing ability will get them back on track.
The 31-year-old has already been a big hit at the iPro and if he can fire them to promotion, he will become even more of a fans' favourite.
