NBCSports.com reported Wednesday that wide receiver Jeremy Maclin has mononucleosis - or something like that.

So far there's been no confirmation by Maclin or the Eagles, although that could come when trainer Rick Burkholder speaks on a conference call at 7 p.m. Wednesday.

Mononucleosis is a viral infection causing fever, sore throat and swollen lymph glands, especially in the neck according to healthline.com. It can lead to an enlarged spleen or liver, hepatitis, jaundice, severe muscle fatigue and weight loss, among other symptoms.

The testing process isn't necessarily conclusive and all ranges of maladies must be ruled out, sometimes even cancer.

Mono is called the "Kissing Disease" because of one of the ways it may be passed on. It is a very common infection in young people although it can affect any age group.

During the offseason Maclin said he had mononucleosis but felt he was recovered. Full recovery can take weeks or months.

If it is mono, head coach Andy Reid's timetable for a return might not sound so totally insane. Big Red said he was "optimistic" Maclin could be ready for the regular season opener.

That said the Eagles, according to DeSean Jackson, signed veteran wide receiver Steve Smith "as insurance" if Maclin cannot make a rapid recovery.

Reid, Maclin's brother and general manager Howie Roseman all said Maclin will be back this season.
