Technical Staff

Michael Nsien - Head Coach

A Tulsa native, Michael Nsien grew up in the Greenwood District of downtown Tulsa, attending Booker T. Washington High School. Following a playing career that saw Nsien star at the University of Dayton and spend time with the LA Galaxy in Major League Soccer, Nsien's career shifted towards coaching.

After showing promise as a youth soccer coach in Tulsa, Nsien was added to FC Tulsa's (then known as the Tulsa Roughnecks FC) coaching staff in 2017. Midway through the 2018 USL Championship season, Nsien was named the interim head coach, taking over a club that was 0-8-7 at the time. He secured a victory in his professional head coaching debut, a 2-0 win over LA Galaxy II. 


On December 7, 2018, Nsien was named the full-time head coach of Tulsa. In his two seasons as the full-time head coach, Nsien has compiled a record of 14-18-17, while leading FC Tulsa to a USL Championship Playoff berth in 2020. Under his leadership, the 2020 season was the best in Tulsa's six-year USL Championship history as the club made the Playoffs, compiled a franchise-best seven match unbeaten streak and had the club's best-ever defense. 

Nsien currently holds USSF "Pro" and his UEFA "A" coaching licenses. In December of 2020, Nsien became the first African American coach to earn his USSF Pro License. He has spent time learning the coaching profession with historic European clubs Benfica, Liverpool, Manchester United, and Manchester City at their respected academies.

Donovan Ricketts - First Assistant

The legendary Jamaican goalkeeper Donovan Ricketts returns to FC Tulsa for the 2021 USL Championship season as the team's First Assistant Coach. A USSF "B" license holder, Ricketts will serve as the top assistant to head coach Michael Nsien and train the goalkeepers.

Ricketts' goalkeeping résumé speaks for itself. One of the greatest players in Jamaican National Team history, Ricketts made more than 100 appearances for his country on the international stage, often serving as his country's captain. He competed in numerous CONCACAF tournaments including Gold numerous Cups and 2010 World Cup qualifying. He was a member of Jamaica's 1998 World Cup team.

His club career was just as prolific, as he spent time professionally playing in Jamaica, England and the U.S. He recorded over 100 appearances in England for Bradford City A.F.C. in English League One. 

Ricketts is likely best known for his time in MLS as one of the greatest keepers in league history. He was named the MLS Goalkeeper of the Year twice and won an MLS Cup in 2011 with LA Galaxy. 

Nemanja Vukovic - Assistant Coach

Nemanja Vukovic returns to Michael Nsien's staff for the 2021 USL Championship season at FC Tulsa as an Assistant Coach. Vukovic is no stranger to Tulsa, having played under Nsien with the Tulsa Roughnecks in 2018 and serving as an Assistant Coach in 2019 and 2020. 

Born in Titograd, Yugoslavia, "Vuko" had a professional soccer career that spanned over 15 years, including stints in the U.S. playing in MLS with Columbus Crew and in the USL Championship with Indy Eleven, Sacramento Republic FC and Tulsa.

While with Sacramento Republic in 2014, Vukovic won the USL Championship title and was named the league's

Defender of the Year. He made the All-USL First Team in 2014, the All-USL Second Team in 2015. Vukovic played in the 2016 NASL Soccer Bowl with Indy Eleven in 2016, falling to the New York Cosmos in penalties.

Cyprian Hedrick - Assistant Coach

A familiar face returned to FC Tulsa’s touchline for the 2021 season, as retired FC Tulsa defender Cyprian Hedrick was been added to the technical staff as an Assistant Coach just before the season opener. Hedrick joined Head Coach Michael Nsien, First Assistant Donovan Ricketts and Assistant Coach Nemanja Vukovic on the 2021 coaching staff. Hedrick spent the last two seasons of his prolific pro soccer career in Tulsa, serving as the club’s Captain during the 2019 season.

Over his eight-year USL Championship career, Hedrick appeared in 167 regular season USL Championship

matches, playing nearly 14,000 career minutes. He ranks in the top 15 in league history in both categories… The now 31-year-old made the USL Championship Playoffs in four of his eight seasons in the league, reaching the Western Conference Finals in 2016 with OKC Energy FC.

Hedrick’s final two seasons as a professional came in Tulsa as he signed with Nsien and the then-Roughnecks prior to the 2019 season. An incoming veteran with a wealth of experience, he was named the Captain in his inaugural season in Tulsa and appeared in 33 matches, playing every minute of all 33. While he battled injuries in 2020 which limited his playing time, Hedrick’s leadership in the locker room was a critical piece in the turnaround of the franchise during the first season of the Craft brothers’ ownership and the FC Tulsa era.
