Gallen said he tweaked the knee during the match but the Blues captain believed it would not put in doubt for State of Origin II on Wednesday week.
"I was about to go back on, then they got that (Hayne) try ... so Flanno (coach Shane Flanagan) said 'don't worry about it'," Gallen said after the match.
The Sharks produced an almost perfect opening 40 minutes, with the 20-6 halftime scoreboard doing little to reflect their dominance as they completed a remarkable 21 of 22 sets.
Such was the precision of Carney's kicking game - save for a shanked cross-field kick which went 20 metres backwards - the Eels were forced into four line drop outs, that pressure telling as the Sharks ran in three tries.
Parramatta scored the first try when Hayne put Ryan Morgan over, but it wasn't long before Isaac Gordon and Colin Best scored to have the Sharks on top.
The Eels would have been happy to go to sheds trailing by just eight, only for Gallen to go over from dummy half just before the break.
A Ben Roberts bust sparked the Eels to life and three defenders were unable to stop Hayne before Carney relived an Origin I moment he'd rather forget when he failed to find touch from a penalty.
Burt's effort to secure a repeat set was rewarded when he scored on the next set before a Morgan bust put him over again to give the Eels the lead ten minutes from time.
