Blackpool boss Ian Holloway has received a one-match touchline after being charged with improper conduct by the Football Association for comments made during Tuesday's draw at Coventry.
Holloway claimed fourth official Guy Stretton prevented him from making a substitution before a Coventry corner which led to a goal for Gary Deegan.
The charge is for using insulting or abusive language and behaviour amounting to improper conduct.
He has also been fined £2,000.
Holloway was given a one-match ban in October for admitting swearing at referee Mike Dean in the tunnel following the 2-1 defeat against Blackburn.
On that occasion he was also fined £9,500 for his outburst.
