The Leicester loanee has returned to the club after recovering from his cruciate ligament injury, sustained back in September.
But Ward, back for a second spell with the Pirates, is set to be without captain Matt Gill as the former Norwich man is still sidelined with a knee problem.
And with only five days between his unveiling as Rovers' second manager in 12 months and their clash with Steve Evans' side, Ward knows time is of the essence as he gets to know his new squad.
"I've got to trust my own eyes and rely on a number of other people, staff and maybe the players," he told Press Association Sport. "I'll be chatting to them and finding out what their mood is and what they feel. The players will have done their homework on me and I've got to do my homework on them and find out.
"The next two or three games are important for them and me and the next 24 are vital for all of us."
