Lankinen will guard the road goal versus the Senators on Tuesday, Brendan Batchelor of Sportsnet 650 reports.
Lankinen will handle the second half of a back-to-back after Nikita Tolopilo played Monday in a 6-3 loss to the Canadiens. Lankinen is winless in his last three outings, allowing nine goals on 64 shots in that span, which makes him a risky fantasy option for Tuesday's schedule.
