Ihsan came up through the youth teams of Irbid club Al-Arabi until making his debut for the first team in 2011, aged 17. He made over 50 appearances for the club over the following 3 seasons before spending the next 3 seasons playing for Al-Ramtha and Al-Hussein, Irbid's two biggest and most popular clubs. After proving himself to be one of the country's most promising young players, Ihsan started attracting attention from the big clubs in the capital Amman.
In the summer of 2017, Haddad completed his move to Amman club Al-Wehdat. He spent one season at the club where he won the Jordanian Pro League, the first trophy of his career. After less than a year at the club and having cemented himself as one of the best players in the league, he signed for arch rivals Al-Faisaly, the most successful club in Jordanian football history and the most supported club in the country.
Haddad would go on to become a legend at Al-Faisaly, winning six titles with the club, so far, and captaining them on numerous occasions as they won every possible trophy within Jordanian football as well as representing them in the AFC Cup and the AFC Champions League.
In January 2021, Ihsan signed for Iraqi giants Al-Quwa Al-Jawiya where he immediately became a fan-favourite and one of their best players, playing all but two of the club's Champions League matches in Saudi Arabia as well as scoring the winner against arch rivals Al-Zawraa in the Iraqi Clasico. He would end his first season in Iraq winning the double as Al-Jawiya won the Iraqi Premier League and the Iraq Cup. Haddad terminated his contract and left the club in 2022 amidst disagreements with the club's administration, returning to Al-Faisaly and winning the 2022 Jordanian Pro League.
Following the end of the 2022 Jordanian season, in November, the league was changing the calendar ahead of the next season, which would not start until the following September, leading many Jordanian players to sign short-term deals at other clubs in the Middle East. Haddad would return to Iraq, signing for defending champions Al-Shorta on a short-term deal until the summer of 2023 where he would win his second Iraqi Premier League title.
Upon returning to Al-Faisaly, Ihsan helped his side win the Centennial Shield, going undefeated.
In July 2024, Ihsan signed a one-year contract to Al-Hussein, making his return to the city of Irbid.[7]
International career
Ihsan has represented Jordan at every national team level, starting with the U16s in 2009 until he made his debut for the senior team in 2013. He has since gone on to win 75 caps for his country and now captains them.
He led Jordan to the quarter-finals of the 2021 FIFA Arab Cup, the first time the tournament was held under the jurisdiction of FIFA.
Haddad captained Jordan to a historic tournament at the 2023 AFC Asian Cup as Jordan, who were not even expected to progress out of their group, went all the way to the final, eventually losing to hosts Qatar in a controversial match but knocking out Asian powerhouses and previous champions Iraq and South Korea along the way. Ihsan became the first Jordanian captain to lead his team to a final at a major tournament.
