Jason Robinson and Martin Corry appear to be the major casualties of the Lions' first Test disaster after being selected to play Manawatu on Tuesday. Robinson, replaced after a poor display at full-back against the All Blacks, will start on the right wing.
Corry, who took over the captaincy on Saturday after Brian O'Driscoll's injury, plays at blind-side flanker.
Head coach Sir Clive Woodward insisted, however, that it did not necessarily mean they would miss the second Test.
"Competition is intense," he said. "There are some involved on Tuesday who will also be involved in the Test."
Even so, it is unlikely either Robinson or Corry will be asked to start three matches in eight days. Neil Back could be another casualty after being named on the bench against Manawatu.
The absence of Lewis Moody from Tuesday's 22 suggests he could replace his Leicester team-mate at open-side flanker for the second Test.
Ryan Jones is likely to start at number eight after his outstanding contribution since joining the tour, while Simon Easterby could replace the injured Richard Hill at blind-side.
Gavin Henson, who many believed should have played in the first Test, will not play against Manwatu because of a slight groin strain.
But if the Welshman recovers in time, he should feature in the second Test.
Stephen Jones, Dwayne Peel, Ben Kay and Gethin Jenkins were also not considered for Tuesday's match because of minor knocks.
Wales lock Brent Cockbain, who has arrived in New Zealand as a replacement for the banned Danny Grewcock, will start on the bench. Scottish hooker Gordon Bulloch will captain the side for the second time on tour, while either of the locks, Donncha O'Callaghan or Simon Shaw, could be promoted to the Test team with a strong display.
"Following Saturday's disappointing performance, tomorrow is a big opportunity to regain momentum and get everyone in the right frame of mind before the second Test, which I believe that we can win," said Woodward.
