Burnley manager Nicky Hayen has delivered a mixed injury update ahead of Wednesday's Championship match against Middlesbrough. The Clarets, currently 22nd in the league with just one point from three games, face a significant squad challenge as they prepare to host the fifth-placed side at Turf Moor.

Club captain Josh Cullen made his first return to training on Monday after a lengthy absence due to an ACL injury suffered at the end of December. His comeback, captured in social media images posted by the club, provides a major boost. Teammate Enock Agyei also resumed training on the same day. Hayen highlighted the importance of Cullen's return, stating, "That's the nicest thing to see that the player comes back on the pitch having that smile, but he comes also with a lot of positive energy so this is important also for the group to see that maybe also this is a spark that we can use." However, the manager tempered expectations, adding, "They still need a few weeks, of course."

Defender Bashir Humphreys is set for a lengthy spell on the sidelines. The 23-year-old, who missed the recent games against Bradford City and Norwich City, has been diagnosed with a knee injury. Further tests confirmed the issue will keep him out for approximately eight weeks. This forces a reshuffle in defence, with Connor Roberts likely to continue at left-back against Middlesbrough.

Lucas Pires remains in concussion protocol following an accidental head clash in the cup tie at Bradford. He missed the trip to Carrow Road and will not be available for selection for another 10 to 12 days, ruling him out of the midweek fixture. In midfield, Josh Laurent serves a one-match suspension after being dismissed at the weekend. Long-term absentees Jordan Beyer, Jaydon Banel, and Ashley Barnes also remain unavailable.

There is positive news regarding Oliver Sonne. The player, who was absent at Norwich with a knee problem, has recovered and will be included in the matchday squad for the Middlesbrough game. His availability offers Hayen an additional option as Burnley look to improve their recent form, which reads LLD. The team has conceded nine goals while scoring only four in their opening three league matches, leaving them with a negative five goal difference.

This injury update comes at a critical time. Burnley's difficult start sees them eight points behind early leaders Charlton. The visit of a strong Middlesbrough side, sitting fifth in the table, represents a tough challenge. Hayen will need to carefully manage his available resources. Fans can track the team's progress and upcoming challenges on the club's fixtures and standings pages.

The match at Turf Moor is scheduled for Wednesday, September 2nd, 2026. Securing a positive result is important for Burnley to climb from their current lowly league position and build momentum.
