Why is Rio Ferdinand not on commentary for TNT Sports during PSG vs Arsenal?

RIO Ferdinand will not be a part of TNT Sports' coverage for Arsenal's Champions League semi-final second leg away at PSG this evening.
The Gunners are looking to overturn a 1-0 deficit following Ousmane Dembele's strike in London last week.

Les Parisiens historically do not perform well in home Champions League semi-finals, so the Gunners will be given a boost before the clash even kicks off.
PSG have appeared in the competition's final more recently than the Gunners, having been there in 2020, with Arsenal not appearing since 2006.
Both sides are aiming to lift the iconic Champions League trophy for the first time in their history this season.
Rio Ferdinand confirmed via X that he will miss tonight's match after being hospitalised.
The former Man Utd defender posted: "Gutted to be missing the Semi-Finals this week on @footballontnt!!"
"Wishing the team all the best — I’ll be watching every minute from the iPad!"
TNT Sports replied to the post by saying: "Get well soon, Rio."
SunSport understands his condition is not serious.
