Transact SQL :: UPDATE With OUTPUT Clause

I am trying to update a table and then also use OUTPUT clause to capture some of the columns. The code that I am using is something like the one below

UPDATE s
SET Exception_Ind = 1
OUTPUT s.Master_Id, s.TCK_NR
INTO #temp2
FROM Master_Summary s
INNER JOIN Exception d
ON d.Id = LEFT(s.Id, 8)
AND d.Barcode_Num = s.TCK_NR
WHERE s.Exception_Ind IS NULL

The above code is throwing an error as follows:

Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113
The multi-part identifier "s.Master_Id" could not be bound.
Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113

The multi-part identifier "s.TCK_NR" could not be bound.
