Brook beat Jones at a cache-weight in his first fight since October following numerous injury problems.
The 27-year-old reveals that he will be back in the ring in September against a "big name" as he aims to get back into world title contention.
"I weren't too excited by that performance," Brook told Sky Sports afterwards.
"I came here to have fun tonight. Jones is a tough customer, I hurt my hand on his head. I got the rounds in though, it was win-win for me.
"It's been a difficult nine months, the hardest ever. I'll be back in the gym on Monday and I'll have a big name in Sheffield in September. You'll see a different animal then, back at my natural weight."
Brook twice had world title fights with Devon Alexander called off this year and will be targeting another big win later in the year.
