Wycherley was an unused substitute in Munster's fixture against Welsh side Scarlets in Thomond Park on 24 February 2017. This was his first call-up to the senior Munster team in a United Rugby Championship fixture. On 4 March 2017, Wycherley made his competitive debut for Munster when he came on as a replacement in the 2016–17 Pro12 fixture against Cardiff Blues in Cardiff Arms Park. In Munster's 2017–18 Pro14 defeat against Glasgow Warriors on 22 September 2017, Wycherley was sent off. He was subsequently cited and banned for three weeks.
