Pat Fenlon feels "a little bit guilty" after Gary Deegan's fractured jaw in an alleged assault but will not put a curfew on Hibernian players.
Irishman Deegan, a summer signing from Coventry, required surgery after the incident, which came following a night out after the 3-0 win over Dundee which took Hibs top of the SPL.
Hibs, now two points behind Celtic in the SPL standings, play Ross County on Saturday without Deegan.
Fenlon said: "It's very frustrating. I'm disappointed for Gary. It's a police matter now and we've got to let them do their job and deal with it.
"I'm disappointed for him and feel a little bit guilty myself.
"I brought him here to play for this club and tried to convince him it was a great place to live and a great place to play football.
"Something like that happens, you feel a bit guilty.
"He's come in, he's been a great part of the place and we'll make sure we look after him and he gets himself right."
Fenlon will not be placing restrictions on his players.
He said: "I can't lock them up seven days a week. It's an unfortunate thing.
"It happens in every city in the world but when it comes home to you it's disappointing."
Defender Tim Clancy is rated 50-50 with a groin problem for the trip to Dingwall.
"We'll see how he is on Friday morning and make a decision on him then," Fenlon added.
Fenlon knows Hibs will have to continue their form from before the international break at Victoria Park after the two-week hiatus.
He said: "They've had a fabulous start to the season. We know we're going to have to play well to get anything out of the game."
Fenlon spent part of the international break in his native Republic of Ireland. He saw Giovanni Trapattoni's beaten heavily by Germany last Friday, Shamrock Rovers versus Derry in the Airtricity League on Saturday and schoolboy matches on Sunday.
He also kept an eye on his charges and was impressed by the performance of left-back Ryan McGivern in Northern Ireland's draw with Portugal.
Fenlon added: "I thought he was very good. Northern Ireland were excellent."
