Great Britain women's hockey coach Danny Kerry insists players omitted from his squad to play in next week's Olympic test event still have a chance of making the cut for London 2012.
Only two of the 18 named did not feature in February's silver medal-winning Champions Trophy squad, but Kerry stressed that did not mean those who missed out should give up hope or those selected should be complacent.
The test event, being staged at the Olympic Park from May 2-6, against Korea, China and Argentina, is the last event before selection for this summer's Games takes place.
"The final Olympic team will not necessarily come from this squad," said Kerry. "Korea and China will both be in our pool for the Olympic Games and so there will also be an element of keeping back aspects of our game."
Kerry has opted to pick only one goalkeeper - Reading's Beth Storry - in order to give more players a chance over the four-day competition.
"We have decided to only name one goalkeeper to facilitate looking further at outfield options," added the coach.
"Our primary aim at the test event will be looking at combinations of players across certain lines to assist our thinking toward the final Olympic Games (squad) and to continue to evolve our play.
"We feel very capable of matching these world-class teams but the focus ultimately will be on preparing for the Games themselves. Results in this respect are secondary to our Olympic preparation."
Leicester's Rebecca Herbert and University of Birmingham's Susie Gilbert both return after missing out on the Champions Trophy.
