I’m guessing that when a player carrying an injury has a medical, extra tests are carried out to assess both the prognosis, and whether it’s masking any underlying conditions.
Is the club not announcing the Stewart signing out of sensitivity to Sunderland given the game today?
I suspect that the actual deal was done much earlier, I am guessing that Ross travelled back to Newcastle with the squad, in the Saint's chariot (G-ISLM ATR 72 Blue Island) around 4 p.m. There may have been some i's to cross and t's to dot which may have delayed the final announcement, but it was probably a deal with Skysports to keep up the interest?
