  The helicity-dependent observable $E$ for the reaction $\gamma d\to \eta n
(p)$ with a spectator proton was recently measured by the A2 Collaboration at
MAMI in Mainz. The data were interpreted as further evidence for a narrow
resonance with spin and parity $J^P=1/2^+$ ($P_{11}$ wave). However, a full
partial wave analysis without any narrow resonance leads to an excellent
description of the data, imposing a narrow resonance with the properties
suggested by the A2 Collaboration leads to a significant deterioration of the
fit quality: there is no need for a narrow resonance.
