The American defender is set to join the New England Revolution on trial ahead of the MLS transfer window closing.
Packwood’s deal was set to expire on June 30 but, with the MLS transfer window closing on May 12, the 21-year-old American defender requested that it be cancelled early to allow him to join the Revs on trial.
Born to an English father and American mother, the Massachusetts-native first left the States in 2007 to join Birmingham, before progressing through the club’s ranks to earn his first-team debut in March 2012.
He would go on to make 21 total appearances for the Blues over the following three seasons but saw his time at St Andrew’s disrupted after suffering a serious leg break in January 2013, which kept him out for several months.
The team remained faithful to him during his spell on the sidelines, even offering him a contract extension, but the US Under-23 international would struggle to hold down a place in the squad following his return to action.
After spending part of last season on loan at Bristol Rovers, he featured just once for the Blues this term, taking in further short-term spells at Colchester United and Cheltenham Town before his release.
Nevertheless, the versatile Packwood remains a well-regarded prospect within the US national team setup and even earned a senior call-up in March 2014, when he was unused substitute for a 2-0 defeat to Ukraine.
He is still to make his debut for Jurgen Klinsmann’s side but a move to his local MLS club, where he has the chance of regular first-team football, could be his best chance of getting back on the German’s radar.
The move also makes clear sense for the Revs, who are in need of defensive reinforcements after losing Darrius Barnes to torn patellar tendon last month, while Packwood's ability to fill in at centre-back, right-back or defensive midfield is an obvious plus point.
