+Let $M$ be a marked $n$-ball, $b \in \cM(M)$, and $f: M\to M$ be a homeomorphism which 
+acts trivially on the restriction $\bd b$ of $b$ to $\bd M$.
+Suppose furthermore that $f$ is isotopic to the identity through homeomorphisms which

+Then $f(b) = b$.
 In addition, collar maps act trivially on $\cM(M)$.
