Heaton spent less than two weeks back at Manchester United before going back out on loan to Wycombe Wanderers on 12 February 2010. He went straight into the Wycombe starting line-up for their away match against Brentford the following day, which they drew 1–1. Heaton made his second appearance for the Chairboys in their 0–0 draw against Southampton on Tuesday 23 February 2010. He made a great save from a volley to keep the Chairboys on even terms with the Saints.
