"We just feel it's a little bit harshly graded and we'll go down there and take our chances," Cartwright said.
"You take everything into consideration. If we didn't think we could get him downgraded, we wouldn't go down and waste our time.
"We believe it was slightly on the high end of the grading and we'll go down and contest that. Hopefully we can get it down to a week and get him right for the Cowboys game [on June 2]."
Taylor was one of three players from the 32-6 loss to the Broncos unavailable for the clash with the Eels, along with injured pair Beau Falloon (broken ankle) and David Mead (broken jaw).
Cartwright has chosen young prop Mark Ioane to take Taylor's spoton the interchange bench while Anthony Don will replace Mead on the wing.
Matt Srama moves into the starting team at hooker in place of Falloon, with youngster Sam Irwin coming on to a five-man interchange bench with Luke O'Dwyer the 18th man.
Cartwright said Sunday's game loomed as a crucial one for the Titans.
"It's a really important game for us leading into a Cowboys game where we're going to be without the Origin boys," he said.
"Every game takes on pretty much a major importance now."
