The one-match ban issued to Slavia Prague defender Ondrej Kudela "does little to instill confidence" in UEFA's approach to eradicating racism, says Rangers player Glen Kamara's lawyer.
Kudela, 34, denies Kamara's claim he racially abused him during Slavia's 2-0 Europa League win at Ibrox on 18 March.
The Czech has been given a provisional suspension for insulting an opponent while UEFA investigate the allegation
If found guilty of racism, he could face a 10-match ban.
UEFA says it is also investigating Kamara's behavior. Slavia claim Kudela was assaulted in the tunnel after the match in Glasgow.
Kudela will miss Thursday's quarter-final first-leg meeting with Arsenal. However, he was expected to be absent for the game in London anyway, owing to an injury sustained against Wales on duty with the Czech Republic.
A statement from UEFA concludes that more information "will be made available once the CEDB [Control, Ethics and Disciplinary Body] has taken a decision in due course".
