Star Parramatta duo Jarryd Hayne and Tim Mannah are in doubt for the Eels' NRL season opener next month after both players suffered knee injuries in their 26-10 trial loss at Penrith.
Fullback Hayne had to be helped from the field in the 70th minute after he landed awkwardly while attempting to catch a chip-kick from new recruit Chris Sandow, while Mannah limped from the field early in the second half.
The Eels coach Stephen Kearney was optimistic when asked if either player was in doubt for their round one clash against Brisbane, but admitted they could face two or three weeks on the sideline.
Hayne was also upbeat, despite admitting his knee went numb instantly, and said he would know more after he had scans.
