Bangladesh dropped Liton Das for Monday's third and final one-day international against Sri Lanka after the veteran opener was humiliatingly dismissed for consecutive ducks in the first two matches.
One-day debutant Jaker Ali will take Liton's place after a solid performance from the wicketkeeper-batsman in the T20 leg of Sri Lanka's tour, won by the visitors 2-1.
Liton by contrast also struggled in the 20-over series, scoring just 44 runs in three matches.
"Considering Liton's recent performance in white-ball cricket, we opted for this change, mindful of the availability of two other capable openers within the squad," chief selector Gazi Ashraf Hossain said in a statement.
"With the series now hanging in the balance, we believe Jaker Ali's addition will provide the team with more options and flexibility in the middle order," he added.
Jaker, 26, has averaged 55 in his six T20 appearances for Bangladesh.
The ODI series is tied 1-1 after Bangladesh won the opener by six wickets, with Sri Lanka taking the second by three wickets on Friday.
Chittagong hosts the final match on Monday.
