Watmore has been absent through an ankle ligament injury.
Watmore has been sidelined through an ankle ligament injury he picked up in the 2-2 draw with Liverpool at the start of February but is ahead of schedule in his recovery.
The 22-year-old is said to have started running and will be a welcome boost for Sam Allardyce in the club's quest for Premier League survival.
The Black Cats are currently two points adrift of Norwich in the relegation zone and could do with as many of their options available as possible.
It means what Watmore could be available for Sunderland's clash with Arsenal on 24th April, with remaining games following against Stoke City, Chelsea, Everton and Watford in what looks as though it could be a tricky run-in for the side.
Given that Sunderland have not been able to fix the problem of leaking goals at the back so far, it might be the case that a little more firepower at the other end of the field could be the answer to their prayers, and they might have to outscore their opponents during the run-in to stay up.
Watmore is a player that generates some excitement and can be a handful for the opposition, and it's hard to think that he won't feature when he's available for the final few games.
