Both had been training with the first team since the restart in May, and each has now been handed a two-year contract.
Centre-back Dinger, 19, played 13 games for the club’s under-19s last season, whilst Rabold, also 19, played 17 matches from right-back as captain for the side.
There are now six homegrown prospects in the first team squad. David Trivunic had already been given a professional contract in June, whilst Malik Batmaz, Janis Hanek and Dominik Kother are the others.
“Our academy stands for excellent youth work, which is now also evident in the development of Janis and Marlon into professional players,” says sporting director Oliver Kreuzer.
“The pair have completed their football training here for years and are now ready for the next step,” he continued.
Further new arrivals, including cover at left-back, are still wanted by coach Christian Eichner, but finances could be an issue in the wake of the coronavirus, with the club’s report reportedly already exhausted. A move for Freiburg’s Florian Kath is apparently hanging due to cost.
