Two home games remain, against Wolves on Easter Monday and Newcastle four days later, but tonight's game represents the last chance to take a rare three points on the road.
In a season of much change, that's something on achieved once in the league, at Norwich. The Canares now languish bottom of the table, Stoke second bottom with Boro one place above.
Just two points separate all three, who are all away tonight, with Norwich having played a game more.
West Ham will be all out to maintain their promotion push. The Hammers currently sit in fifth, the final play off position, but just three points off second placed Fulham. Swansea, who Boro beat early in the campaign, won the league a long time ago and currently sit 13 points clear.
Earlier in the day Fulham are at fourth placed Newcastle, so West Ham are well placed to take advantage of any slip up by either of those two. Third placed Wolves are are home to Norwich tonight.
"I have told the lads to go out and end the season on a high," says Lee.
"This s a great chance for them to show what they can do in a great stadium on a Premier League surface, this is one to look forward to.
"There are still some playing for contracts for next season, so there is still a lot at stake."
Kick-off is 7pm.
