When they were finally cleared, referee Darren Handley got the game under way. However, more pigs were thrown onto one corner of the Ricoh Arena pitch within seconds and the two teams set off down the tunnel to wait for them to be cleared again.
When the game got going, Charlton struck the bar in the 20th minute as Nathan Byrne got his head to Jay Dasilva's perfect cross.
But it was the home side who took the lead in the 28th minute after a clever corner. Thomas took it short and, after a neat passing move, it was Thomas who found himself eight yards from goal to supply the crucial finish.
Coventry had two great chances to give themselves a cushion at the start of the second half but Thomas was denied by Declan Rudd before Jodi Jones shot wide after a quick break.
Charlton drew level in the 55th minute as Ricky Holmes' corner was headed in by Bauer from inside the six-yard box.
Coventry almost went ahead 10 minutes later but Thomas headed wide when Jones' shot was parried back to him by Rudd and, moments later, the goalkeeper made a great one-handed save to deny Thomas again.
