Forster has made just one appearance from the bench this season
Gloucester prop Jack Forster admits the team are looking "nervous" as they deal with injury problems.
The 21-year-old returned to first-team action on Saturday against the Dragons at Kingsholm after recovering from a thumb injury.
He told BBC Radio Gloucestershire: "We are still playing a little bit nervous.
"What's happened recently, not only is someone being injured but they're being replaced by someone who has just come back from injury, which isn't ideal."
"Everyone's still thinking the last couple of weeks, we have not done what we've wanted to do.
"I think we will look at it again to take some chances and get a good win but it is also a chance to really get the team itself going forward as a unit."
The Cherry and Whites will take on Newcastle on Sunday in the final EDF Energy Cup Pool A game at Kingston Park at 1500 GMT.
