With the rest of the back-end relatively healthy, the 6th and final spot in the lineup will be fought over between Dakota Mermis and Phil Myers. The former has played in 2 games with the Marlies and 1 with the Leafs, whereas the latter has appeared in 4 games at the NHL-level, giving him a slight edge for Monday's game versus Pittsburgh.
With 2 serious injuries within a span of 2 weeks, the Leafs will more than likely be very cautious with Tanev and his return to play process. The 36-year-old is a key component of their defensive unit, but his health is of the utmost importance.
