Marcus Bettinelli has started every league game for the Teessiders this campaign, following his season-long loan move from Fulham, but hasn’t been convincing between the sticks.
The 28-year-old made a costly error for the opening goal in a 2-0 defeat at Barnsley last time out and has been caught out on other occasions during the 2019/20 season.
Boro’s second-choice keeper Jordan Archer will also be out of contract this summer, meaning the Teessiders could be looking to sign two new stoppers over the next few months.
With several players set to become free agents this summer, Boro will undoubtedly be exploring that market while loan deals are also a possibility.
We’ve picked out nine goalkeepers who are currently contracted to Premier League and Championship clubs who Boro could target.

1. Bartosz Bialkowski (Millwall)
Only Swansea's Freddie Woodman and Norwich's Tim Krul have kept more clean sheets than Bialkowski in the Championship this season. The 33-year-old was voted Millwall's Fans' Player of the Season last year and has proved himself at Championship level.

2. Neil Etheridge (Birmingham)
A man who Boro were tracking last summer but finances proved tricky. Etheridge, who played for Warnock at Cardiff, is under contract until 2024 but has been part of a struggling Birmingham side this season.

3. John Ruddy (Wolves)
The experienced stopper has won promotion from the Championship with both Norwich and Wolves. The 34-year-old will be out of contract at Wolves this summer after playing No 2 to Rui Patricio.
4. Wayne Hennessey (Crystal Palace)
Another Premier League goalkeeper who hasn't been playing this season and will be out of contract this summer. Hennessey, 34 is still a regular for the Welsh national team.
