The Three Lions boss admits that it was a blow to lose out on the defender's services but is reticent to suggest that it could spell the end of the defender's international career
The Manchester United defender withdrew from the squad in order to pursue a "pre-planned fitness regime" but has now been revealed to be travelling to Qatar in order to work as a pundit for local television.
Hodgson told the press: "I don't have any serious thoughts. I was disappointed when he couldn't join up with us because I picked him as one of our four defenders.
"What he does now and how he operates in the coming couple of weeks is his business and the club's business. I'm not really interested in the players that aren't here.
"I just look at the players that are here in the squad and worry about them. It would have been nice for Rio to be here but he's not and we move on without him."
The Three Lions boss refused to be drawn on whether this spells the end for Ferdinand's international career, suggesting that fitness will play an important part in the decision.
"It's more a question of how his injury situation will impact on him playing for England," he explained. "We will see. It is speculation about a long-term future but I am only focusing on the next two games."
Ferdinand's absence has been compounded by an injury to Gary Cahill, who will miss the Montenegro game as well as San Marino, but Hodgson insists that he has confidence in the remaining quartet of Joleon Lescott, Chris Smalling, Steven Caulker and the uncapped Steven Taylor.
"I learned today that Gary Cahill won't be able to join us, after we left the door open to him it's not a great surprise," he continued, "but I have been really happy with the center backs I have got here. It is up to them to make it their good fortune after other people's misfortune."
"We have got four top players here, they are playing at top clubs and have a lot of experience. I would be loath to start using players like Michael Carrick who has been selected for his prowess in central midfield and it would be harsh on the four central defenders who are here."
