It's down to the wire now for the five contenders who have been shortlisted for the ultimate individual accolade in northern hemisphere rugby, ERC European Player of the Year 2013.
The return of Henosn would be a boost for Jones' depleted side.
"Due to the demands of the autumn internationals not many of our Wales players will feature this weekend," Jones said.
"However, we are taking the game seriously and this is reflected in the strength of the squad we have chosen. Bristol have performed exceptionally well in the Guinness Premiership this year and we will be looking to continue the form we showed in beating Ulster last time out.
"They have a big pack of forwards and have plenty of experience in their backline, but this game will be about overselves and maintaining the performance levels we achieved in Ulster.
It will also mark the start of the buildup to what will be the biggest game of the season at Welford Road next weekend."
Henson had said earlier in the day: "Training has gone very well as I have picked up the intensity over the last few weeks and I am really looking forward to being involved against Bristol.
"Rugby has been my life and I have missed it over the last few months. It has been frustrating sitting on the sidelines and I am excited about getting back on the pitch.
"The success I achieved on the field last season was built on a solid foundation of performing consistently well for the Ospreys and I can't wait to pull on the black jersey this weekend."
Ospreys fans will agree, but now face a nervous wait to see if the talented centre takes to the park this weekend.
