The lively striker limped off with groin trouble after scoring United's second goal in the excellent victory over Portsmouth at Fratton Park.
He pulled up sharp a couple of minutes before his goal, and signalled to the bench he was struggling.
Obviously he gave his famous goal celebration a miss ... for once.
Chris Hughton: "Oba felt his groin go after scoring on Sunday and he was in for treatment yesterday. All we can do is to assess the injury as the week goes on and we should know more in the next couple of days as to the extent of the problem.
Martins Touch-And-Go!
"Obviously, with the holiday period coming up, we want all our players fit and on this score we are as healthy as we have been all season.
"Apart from Oba, we have no other short-term injuries, and this was seen by the strength of our bench at Portsmouth on Sunday.
"In fact, Shola Ameobi came off the bench to replace Oba and set up our third goal for Danny Guthrie and this is the sort of thing we want."
