Abstract
We describe the embedding from the crystal of Kashiwara-Nakashima tableaux in type of an arbitrary shape into that of -Lusztig data associated to a family of reduced expressions which are compatible with the maximal Levi subalgebra of type . The embedding is described explicitly in terms of well-known combinatorics of type including the Sch\"{u}tzenberger's jeu de taquin and an analog of RSK algorithm.
