Windsor-born back row Cracknell, most recently at Bath Rugby, is determined to take his chance to shine at Sixways after signing a deal until the end of the season.
And the 25-year-old admits the positive words of Abbott mean he can hardly wait to get started.
"I'm very excited, my signing has actually been in the pipeline for a couple of weeks so I'm really pleased to put pen to paper," said the back row, nicknamed Crackers.
"I'm just looking forward to joining up with the boys and meeting all the staff and settling in. I spoke to Jake Abbott about the club and had nothing but really positive things to say about Warriors, from the local area to the coaching staff and ambition at Sixways.
"I've played against Worcester a couple of times and already know some of the squad. I was with Pat Sanderson and Matt Powell at Harlequins, spent some playing time with Dale Rasmussen and know Will Bowley from junior England levels.
"I'm also really keen to link-up with Mike Ruddock. I have heard lots of positive things about him; have been impressed by his plans and look forward to getting to know him and how he works.
Cracknell, a strong ball carrying back row who describes himself as a 'true team player' has been a shining star for England Sevens over the past three years and admits the experience has been hugely beneficial to him.
But now he plans to make Warriors his home as he looks to fill the shoes of the injured Netani Talei in the coming months.
He said: "The England Sevens circuit is something I've done for the last three seasons. It's been a fantastic experience. I got to represent my country and seen parts of the world.
"You go from the glitz and glamour of Dubai to George in South Africa which was a bit like going back in time.
"For young players, like Jake (Abbott), it has been brilliant and something you benefit from hugely.
"But now I'm really keen to come and put some roots down at Warriors, make an impact and not just be a squad player. It's a big opportunity for me that has come at the right time."
