However McClennan is confident that 20-year old winger Omar Slaimankhel would continue to take the opportunities that the recent spate of injuries has presented.
"Omar is a real confident kid, he doesn't suffer from any nerves, he believes in himself and it's fantastic. I'm sure he will come up with a great performance for us and he has that ability to come up with something extra too."
It will be the third consecutive start for Slaimankhel and McClennan said he was getting better each week.
"The first game he found out the difference between NYC and first grade, second game he was a bit more aware, and this week he was able prepare with us all week and we have been able to work with him on some of the things he can improve on individually."
McClennan expects the Titans to field a very strong and experienced side with Beau Champion, Luke Bailey, William Zillman and Matt White returning from injury and Nate Miles and Greg Bird likely to feature post Origin.
The Warriors currently sit in ninth place, one above the Titans and are a couple of wins away from getting right back in the finals hunt, and a couple of losses away from irrelevance.
"With nine games to go, we're just taking it one at a time. The Boys feel pretty good after last week's win, we know it's going to be tough on Saturday. It's a very important two points for both clubs.
"One of the things that pleased me last week when it got tight we were able to play with a bit of maturity and close out the game, that hasn't always happened.
"It's an awareness of the situation and game management. That comes from discussion, video and training on the field throwing in different scenarios which the team reacts too."
McClennan will hope that this weekend his side can react to the pressure of equaling their longest consecutive winning run of the season - two matches.
