Baker's conjecture on concordance of tight fibered knots

Let $K_{0}$ and $K_{1}$ be fibered knots in $S^{3}$ supporting the tight contact structure. Baker's conjecture. If $K_{0}$ and $K_{1}$ are concordant, then $K_{0}=K_{1}$. The conjecture predicts that tight, fibered knots are unique in their concordance classes. Its status is not resolved in the supplied text.
