 Following the departure of Christophe Berra to Wolverhampton Wanderers in January 2009, Eggert was given the number four shirt for the 2009–10 season.Perhaps the most memorable moment of his Hearts career came against Aberdeen as he scored an acrobatic overhead kick to give Hearts a 1–0 victory at Pittodrie on 27 February 2010.Due to the absence of captain Marius Žaliūkas and vice-captain Lee Wallace, Eggert was made captain for the 3–0 defeat to Celtic F.C.
