ELLIOT Grandin is unlikely to be back in a Seasiders shirt until the end of October following surgery on a foot injury.
The Frenchman hasn’t played since the home defeat by Derby on August 17.
Grandin had been complaining of a sore foot and underwent an operation as soon as the problem was diagnosed.
Ian Holloway acknowledges he has missed Grandin, who played in the hole between the midfield and attack.
A number of players have been tried in the role but none has enjoyed as much success as Grandin.
New keeper Mark Howard could be on the bench at Coventry.
With Mark Halstead struggling with a small groin tear, 24-year-old Howard – signed on a free after his release by Aberdeen – could be Matt Gilks’ back-up at the Ricoh Arena.
Holloway said: “We’ve been looking for another goalie and I am delighted we’ve got one. Unfortunately, we didn’t get clearance for him to be involved at Portsmouth.
