Leicester Tigers forward Boris Stankovich said injuries have had an impact on the team in recent games.
The prop missed a large part of the season but returned to the Tigers side for the 34-21 win over Leeds Carnegie.
With Marco Wentzel and James Hamilton currently out and Ben Kay on England duty, Martin Corry may have to play in the second row against Worcester.
"At the moment we're a little bit unlucky with the lock situation," Stankovich told BBC Radio Leicester.
"As any front rowers will know that does affect us, especially when it comes to scrum time, so hopefully in the next couple of weeks we can get a few back on board."
Leicester will go top of the Premiership - for a few hours at least - with a win over Worcester at Sixways.

"We're a little bit unlucky with the lock situation"
Corry - who recently retired from international duty - normally plays in the back row but has filled in at lock in the last two games due to injuries.
Tigers head coach Marcelo Loffreda said: "Maybe Martin could be one of the options for that place because now with internationals away we don't have much replacements there."
