Ujah will be considered for selection after doping ban - UK Athletics director
Ujah was provisionally suspended after prohibited substances Ostarine and S-23 were detected in his A and B samples following the men's 4x100m relay final at last year's Tokyo Olympics.
Ujah and his team mates were stripped of their silver medal in February.
Earlier this week, the Athletics Integrity Unit cleared Ujah of intentionally taking the substances and issued the ban, which will be in force until June 5rh 2023.
"If (Ujah) is available to compete we will select him," Maguire told British media on Thursday. "I haven't spoken to CJ in a couple of years. He made a mistake and that's clear, I need to see what the environment is like."
Maguire said everyone would have to be "on the same page" if Ujah is to be reintegrated into the team and that there were several factors to be considered.
"It’s about trust, behaviour and understanding the team aspect. I need to see what the environment is like."
