On 1 January, it was announced that Blackman's loan spell had been extended until the end of the 2016–17 season.

Loan to Sheffield United

On 27 July 2017, Blackman joined Championship side Sheffield United on a season-long loan. He was originally signed as second-choice for number one goalkeeper Simon Moore, however after an injury to Moore in pre-season, Blackman established himself as first-choice goalkeeper. He made his debut on 5 August as the season began with a 1–0 win over Brentford at Bramall Lane. However he was stretchered off after he picked an injury following a collision with team-mate Cameron Carter-Vickers during a 1–0 defeat at Queens Park Rangers on 31 October. He returned to the starting line-up on 17 November, in a 3–1 win over Burton Albion. On 17 March, Blackman received the man of the match award after a string of saves in a 0–0 draw with Nottingham Forest. On 30 March, in a 1–1 draw at Brentford, he and opponent Ryan Woods were sent off for fighting over the ball after the hosts equalised. With Blackman only being at the club on loan, manager Chris Wilder decided to play Moore in goal for the final five games of the season.

On 16 November, he suffered a broken tibia in his leg in a 3–0 defeat in an under-23 match against Birmingham City. Due to the severity of the injury, he returned to Chelsea, leaving Leeds with just one senior goalkeeper in Peacock-Farrell.

Loan to Vitesse On 3 September 2019, Blackman joined Eredivisie side Vitesse on a season-long loan. He reportedly was affected by injury and returned to Chelsea halfway through the 2019–20 campaign without having played a first-team game at the GelreDome.

He made his debut at the Memorial Stadium three days later, in a 0–0 draw with Fleetwood Town. He featured ten times in the second half of the 2019–20 season as Ben Garner's side posted a 14th-place finish. On 5 September, he made his club debut in a 1–1 draw with Salford City in the first round of the EFL Cup. He played 28 games during the 2020–21 relegation campaign as manager Paul Warne rotated between Blackman and Viktor Johansson at the New York Stadium. He made his debut for the club on 29 September, playing the full match in a 2–1 loss to Portland Timbers. On 26 October, Blackman had his first clean sheet with LAFC during the club's 3–0 win over Seattle Sounders FC and was named man of the match by fans. He played the final eight games of the 2021 season, before departing the Banc of California Stadium along with head coach Bob Bradley.
