Leicester signed a number of new defenders for the 2010/11 season which meant that Hobbs was no longer certain of his place in the team, surprisingly considering his player award from the previous campaign. In February 2011 he made a loan-move to Hull City and appeared in 13 Championship matches for the Tigers before signing a permanent three-year deal. Hobbs was named captain in Nicky Barmby's side and was an exceptional performer for the club, but ruptured his anterior cruciate ligament in April 2012.
Hobbs returned to action after recovering from a serious injury and played in twenty-two Championship matches in 2012/13 as Hull City made a return to the Premier League after an absence of three years.
The defender moved to Nottingham Forest on loan from Hull City for the whole of the 2013/14 season with part of the agreement being that after this loan-spell was over he would then sign a two-year contract with the Nottingham club. Hobbs returned briefly to Hull in January 2014 but then signed a four-and-half-year permanent deal with Forest on the final day of the mid-season transfer-window. The defender made 27 league appearances for Forest in 2013/14 as the Nottingham club finished the season in eleventh place, several points and positions behind the play-off places. he also appeared once each in the League Cup and FA Cup. Jack's only goal of the season was the only goal of the East Midlands derby against Derby County at the City Ground in September. In 2015-16 he was a regular in the first half of the season but missed the second half due to a back problem which required surgery. Over the next two seasons he made only fourteen appearances due to a succession of injuries. After being released at the end of 2017-18 he joined Bolton Wanderers, who he was unable to help void the drop to League One. Bolton's financial problems meant he was released, but when a takeover was completed he rejoined them at the end of August 2018, facing an uphill struggle to avoid a second successive relegation.
