New Owls owner Dejphon Chansiri has pledged to spend £1m on laying a brand new pitch at Hillsborough this summer.
The Thai businessman, who completed his £37.5m takeover of the Championship club on Monday, is determined to give head coach Stuart Gray the tools to succeed.
Wednesday have struggled to pick up positive results on home soil and the poor state of the playing surface has not helped their cause.
Chansiri said: “After speaking to Stuart [Gray], it is clear the pitch must be a priority. I have commited £1m in the summer to address this concern with a brand new pitch.
“It is vital we provide the best playing surface for the players if we are to realise our dream of promotion to the Premier League.”
Chansiri, who wants to lead the club back into the top flight within two seasons, also plans to install a new scoreboard at the ground to improve the match-day experience for fans.
Out-of-favour Owls midfielder Giles Coke, meanwhile, has joined Bolton on loan until the end of the season. The 28-year-old has played 16 times this term but has not featured since their goalless draw at home to Rotherham United last November. Coke, out of contract at the end of the season, could make his Trotters debut against Blackburn Rovers this weekend.
