Jennings was dropped by Ivan Cleary for a combination of form and attitude issues but has since apparently received positive reassurances from Blues coach Ricky Stuart.
"Obviously there is a lot [of focus] on myself but I just need to let my game do the talking," said Jennings. "Obviously it is not the right circumstances but you just have to come down with a positive attitude and get through it and do the job for the team."
His side had a difficult afternoon against a red-hot Vulcans side, who stormed back from an early 18-6 deficit to lead 24-18 at halftime.
Ricky Henry's men cantered away in the second half to win 50-30, with sometime Warriors first grade fullback Glen Fisiiahi crossing for three of their nine tries, against the competition's second-best defensive side.
"I wanted to test out [my shoulder] to see where it was at," says Jennings. "We defended all day and they have some big boys so I was thinking it was going to be a good test. I put my body on the line and it came through well."
Jennings featured on attack and didn't manage a line break, while the much anticipated match-up with Krisnan Inu didn't materialise, as the two NRL stars rarely crossed paths.
The far from salubrious ground is used for secondary school athletics as well as club league - if Jennings had made a sideline dash he would have been perilously close to the two long jump pits that run parallel to the perimeter of the field.
Still the presence of Jennings, who has four NSW caps and is on a reputed $770,000 a year at Penrith, was a thrill for players on both sides.
"It was bit daunting seeing him out there," admitted Vulcans winger Dylan Collier.
"You see him on TV and know what he can do. We tried not to give him too much space to move and the coach told us to get up in his face. He is not as big as I thought but he is obviously very quick and strong. [When I'm watching Origin] I'll be bragging to the mates - I played that guy, I put him on the ground."
"I'm not too sure what the circumstances were surrounding him coming back to us but it is great to have him," said Windsor forward Evrett Vaurasi.
