Wolves striker Raul Jimenez said he hopes to "return to the pitch soon" in his first statement since fracturing his skull on Sunday.
The Mexican has had surgery on the injury he suffered in a clash of heads with Arsenal defender David Luiz during Sunday's Premier League meeting.
Jimenez was given oxygen on the pitch at Emirates Stadium before being taken to hospital.
"Thanks for your support messages," Jimenez, 29, tweeted.
"I will be under observation and I hope to return to the pitch soon."
Jimenez had surgery following the game on Sunday, after which a Wolves statement said he was "comfortable".
The club said he had "seen his partner Daniela" and would "remain under observation for a few days".
