Mason re-joined for his third spell at Butlin Road in November 2016 from Chasetown, signing a one-year contract.
Rowley had a torrid third spell with the club after sustaining a broken leg against Coventry Sphinx which all but ruled him out for the season.
He left the club in May 2018.
Mason originally joined Rugby in September 2012 from Barwell.
Strong in the air and the tackle, Mason signed from Barwell as a no-nonsense centre half who formed an excellent, youthful partnership with Alex Gudger.
Rowley was an ever-present for Barwell in the 2011/12 after joining the Leicestershire-based club from Notts County where he was a youth player.
Mason joined as a 19-year-old and the centre back made his debut for Valley in a 1-0 win against Barton Rovers.
After a spell as captain in 2013, Mason left the club in February 2014 to join Stratford Town but returned again in July 2014.
Mason was one of the club's top performers in the 2014/15 season winning the Players' Player & Supporters' Player of the Season awards.
The 2015/16 campaign proved to be a testing one for the club and Mason and he left the club to join Basford in January 2016 where he was part of their play-off campaign and left to join Chasetown in October 2016. |
