Deryn Brace is a former Norwich City trainee who joined Wrexham after failing to break into the City first team. Deryn started playing for the Robins at right back but took over the left back role. According to the Wrexham website, he is"a fan favourite at the Racecourse Ground who is seen as commitment personified and who loves to share his feelings with the crowd. He is a great tackler, enthusiastic pushing forward and, now, comfortable on both flanks making him a very valuable asset in the Wrexham line-up. His performances has earned him 5 Welsh U-21 caps and involvement with the full squad. He has suffered with injuries and was out of action for 5 months after catching pneumonia."

Deryn was given a free transfer on 15th May 2000 and joined League of Wales side Llanelli in the autumn of 2000, playing primarily as a midfielder. During the season, he transferred to Carmarthen. During 2001/02, he moved to Haverfordwest County. On 13th June 2002, County surprisingly announced that Brace was to become their player-manager at the age of 27 ! He replaced John Lewis but will be assisted by former Cardiff player Micky Lewis.

Deryn quit as Haverfordwest's manager at the beginning of October 2006 due to work commitments. He intended to stay with the club as a player under new manager Derek Brazil (ex-Manchester United and Cardiff) but was released two weeks later. Brace, who made 126 appearances for the Bluebirds out of a Welsh Premier total of 138, is said to be interesting two of his former clubs - Carmarthen Town and Llanelli - as well as Port Talbot Town. In the end, Deryn re-signed for Carmarthen.

On 23rd May 2007, Carmarthen appointed Brace as their new manager, following the shock dismissal of Mark Jones who was released just two weeks after winning the Welsh Cup and taking the Old Gold into Europe.
