Walker failed to complete his lone pass attempt in Sunday's 33-31 win over the Ravens.
Walker was brought on for the final play of the first half to throw a Hail Mary pass, after starter Deshaun Watson went to the locker room early to address a gimpy left ankle. Watson played the entire second half -- completing all 14 of his throws during Cleveland's comeback win -- then downplayed the ankle issue following the game. Presumably, Watson will be able to play Week 11 against the Steelers, but Walker remains ready just in case.
